Write a C callable assembler function named "count" that counts the number of times a user-entered character appears in a user-entered string. The function should take two arguments: a pointer to the string and the character to be counted. Use a stack frame and return the count in %eax. Store all data as 32-bit quantities.

#include <stdio.h>

int count(char *str, char c){
    int count = 0;
    int index = 0;
    while(str[index] != '\0'){
        if(str[index] == c){
            count++;
        }
        index++;
    }
    return count;
}

int main(){
    char str[100];
    printf("Please input a string : ");
    scanf("%[^\n]", str);
    char c;
    printf("Please input a char : ");
    scanf(" %c", &c);
    int ret = count(str, c);
    printf("The char %c appears %d times in the string %s\n", c, ret, str);
    return 0;
}
