C program to count the frequency of each character in a string using a for a loop.



#include <stdio.h>
#include <string.h>
#define MAX 100

int main()
{
    char text[MAX];
    int i, len;
    int freq[26];

    printf("\n Enter any string: ");
    gets(text);

    len = strlen(text);


    for(i=0; i<26; i++)
    {
        freq[i] = 0;
    }



    for(i=0; i='a' && text[i]<='z')
        {
            freq[text[i] - 97]++;
        }
        else if(text[i]>='A' && text[i]<='Z')
        {
            freq[text[i] - 65]++;
        }
    }


    printf("\n Frequency of all characters in the given string: ");
    for(i=0; i<26; i++)
    {

        if(freq[i] != 0)
        {
            printf("'%c' = %d\n", (i + 97), freq[i]);
        }
    }

    return 0;
}


Output:


 Enter any string: I love string programming 

 The minimum occurring character in the given string is 'I' = 1.
