Write a C program to calculate the frequencies of different alphabets, present in a given string. The string of alphabets is to be taken as input from the keyboard.

#include<stdio.h>
#include<conio.h>
int frequency ( char    str[], int    j );
void main ( )
{                      
        char       str[70];
        int          i, freq, j;
        clrscr ( );
                       
        printf("\n\n\n\t Enter a string of alphabets..:");  gets(str);
        for ( j = 'a'; j <= 'z'; j++ )
        {                            
                  freq = frequency ( str, j );
                  if ( freq != 0 )
                  {
                             printf("\n\n\t\t\t Frequency of %c = %d",j,freq);
                  }                      
                  freq = frequency ( str, j - 32 );
                  if ( freq != 0 )
                  {                   
                             printf("\n\n\t\t\t Frequency of %c = %d",j-32,freq);
                  }
        }
        getch();
}

int frequency ( char    str[], int    j )
{                                
        int      freq = 0, i;
        for ( i = 0; str[i] != '\0'; i++ )
        {                                
                  if ( str[i] == j )
                  {                     
                               freq++;
                  }
        }
        return freq;
}
