Please find the required program along with its output. Please see the comments against each line to understand the step.
#include \"stdio.h\"
char highestFreq(char *str){
    int count=0,ct,i,j;   //initialize variables
    char c;
    for(i=0; str[i]!=NULL; i++){   //iterate over the string : main loop
        ct = 0;   //set counter for current char as 0
        for(j=i; str[j]!=NULL; j++){   //count the no:of occurence of current char
            if(str[i]==str[j])
                ct++;
        }  
        if(ct > count){   //if current char\'s occurence is > count, then set count as current occurence and c as current char
            count = ct;
            c = str[i];
        }
    }
    return c;   //return c  
 }
int main(void) {
char hf = highestFreq(\"Hello World\");
 printf(\"highestFreq char = %c\",hf);
 return 0;
 }
