Counting the number of vowels and consonants in a given string in C programming(c programming examples)(c program examples)

Counting the number of vowels and consonants in a given string in C programming

This is an example in C program using loops and conditional tools in C. This program can find the vowels and consonants in lower case only. If you want to find the upper case too, use the same conditions once more with the ASCII values of upper case letters. It is very simple with the reference of the above program. 


If you want to see this code with a perfect indentation, copy the code into "sublime text editor" and make sure that the type of code is set to 'c' at the bottom right of the window. After pasting the code press the command "ctrl+shift+P", you get a search box. Type "indentation" you get an option like this below the search box "Indentation: Reindent lines". Clink on that to get the code with indentation. 

The program is as follows:

#include <stdio.h>
main()
{
char a[1000];
int i,vow=0,conso=0;
printf("enter any string\n");
gets(a);
for(i=0;a[i]!='\0';i++)
{
if(a[i]==97 || a[i]==101 || a[i]==105 || a[i]== 111 || a[i]==117 )
vow++;
else if(a[i]>=117 && a[i]<=122 || 
a[i]>=98 && a[i]<=100 || 
a[i]>=102 && a[i]<=104 || 
a[i]>=106 && a[i]<=110 || 
a[i]>=112 && a[i]<=116)
conso++;
}
printf("the number of vowels in the string are %d\n",vow );
printf("the number of consonants in the string are %d\n",conso );
return 0;
}

The output is as follows:

#include <stdio.h>

The '#include' is a preprocessor directive which includes the source files inside the code. The 'stdio.h' is a standard input and output header file with several functions written in it. The functions like 'printf()', 'gets()' and 'scanf()' are work when we include 'stdio.h' header file. 

char a[1000];

The only array 'a[]' is used to hold the entire string entered by the user. The data type 'char' is used to keep the data of characters inside the array.


int i,vow=0,conso=0;

Here we declared three integers 'i', 'vow' and 'conso'. The variable 'i' is used in the loop iterations. The variable 'vow' is used to count the number of vowels in the given string. The variable 'conso' is used to count the number of components in the given string. Both the variable 'vow' and 'conso' are assigned with '0' to remove the garbage value inside the two variable. And the data type we used is 'int'.

printf("enter any string\n");

gets(a);

Here we use the functions 'printf()' and 'gets()', which are the predefined functions in 'stdio.h' header file. The 'printf()' function is used to print the message "enter any string" on the string. The function 'gets()' is used to assign the given string into the array 'a[]'.

  for(i=0;a[i]!='\0';i++)

{

if(a[i]==97 || a[i]==101 || a[i]==105 || a[i]== 111 || a[i]==117 )

vow++;

else if(a[i]>=117 && a[i]<=122 || 

a[i]>=98 && a[i]<=100 || 

a[i]>=102 && a[i]<=104 || 

a[i]>=106 && a[i]<=110 || 

a[i]>=112 && a[i]<=116)

conso++;

}

This is the main component of the program which decides whether the character in the compartment of a string is vowel or consonant. The loop is used to check each individual element of the array. After considering each element the flow of execution goes on. The character is sent through the both conditions. If the ASCII value of the character is in the first condition it represents that the character is a vowel and the value of the variable 'vow' is increased by one. If the ASCII value of the character matches with the second condition the value of 'conso' is incremented by '1'. At the end, the both variable values 'vow' and 'conso' represents the number of vowels and consonants in the string. 

printf("the number of vowels in the string are %d\n",vow );

printf("the number of consonants in the string are %d\n",conso );

The two variable values are printed on the screen by using the function 'printf()'. In the place of '%d' the integer value of 'vow' is printed. Like the same in the next line, the '%d' is replaced by the integer value of 'conso'.  Hence the problem is solved and another program is getting into the bucket.

C is a general-purpose programming language. It has been closely associated with the UNIX system where is was developed, since both the system and most of the programs that run on it are written in C. The language, however, is not tied to any one operating system or machine; and although it has been called a “system programming language” because it is useful for writing compilers and operating systems, it has been used equally well to write major programs in many different domains.(c programming examples)(c program examples)

Many of the important ideas of C stem from the language BCPL, developed by Martin Richards. The influence of BCPL on C proceeded indirectly through the language B, which was written by Ken Thompson in 1970 for the first UNIX system on the DEC PDP-7.(c programming examples)

BCPL and B are “typeless” languages. By contrast, C provides a variety of data types. The fundamental types are characters, and integers and floating point numbers of several sizes. In addition, there is a hierarchy of derived data types created with pointers, arrays, structures, and unions. Expressions are formed from operators and operands; any expression, including an assignment or a function call, can be a statement. Pointers provide for machine-independent address arithmetic.(c programming examples)(c program examples)

C provides the fundamental control-flow constructions required for well-structured programs: statement grouping, decision making (if-else), selecting one of a set of possible cases (switch), looping with the termination test at the top (while, for) or at the bottom (do), and early loop exit (break).(c programming examples)(c program examples)

Functions may return values of basic types, structures, unions, or pointers. Any function may be called recursively. Local variables are typically “automatic,” or created anew with each invocation. Function definitions may not be nested but variables may be declared in a block-structured fashion. The functions of a C program may exist I separate source files that are compiled separately. Variables may be internal to a function, external but know only within a single source file, or visible to the entire program.(c programming examples)(c program examples)

A preprocessing step performs macro substitution on program text, inclusion of other source files, conditional compilation.(c programming examples)(c program examples)

C  is a relatively “low level” language. This characterization is not pejorative; it simply means that C deals with the same sort of object that most computers do, namely characters, numbers, and addresses. These may be combined and moved about with the arithmetic and logical operators implemented by real machines.(c programming examples)(c program examples)

C provides no operations to deal directly with composite objects such as character strings, sets, lists, or arrays. There are no operations that manipulate an entire array or string, although structures may be copied as a unit. The language does not define any storage allocation facility other than static definition and the stack discipline provided by the local variables of functions; there is n heap or garbage collection. Finally, C itself provides no input/output facilities; there are no READ or WRITE statements, and no built-in file access methods. All of these higher-level mechanisms must be provided by explicitly called functions. Most C implementations have included a reasonably standard collection of such functions.(c programming examples)(c program examples)
