Question

Given the following function prototypes: float asciiAvg(char mystring[], int length); Write the function definition. The asciiAvg function should return the average of the ascii values for the characters in the array mystring of length characters.

Answer 1

#include <stdio.h>

float asciiAvg(char mystring[], int length);

int main() {
    printf("%f\n", asciiAvg("Hello", 5));
    return 0;
}

float asciiAvg(char mystring[], int length) {
    int total = 0;
    int i = 0;
    while (mystring[i]) {   // go through each character
        total += (int) mystring[i]; // add character to total
        i++;    // move to next character
    }
    return (float) total / (float) length;  // find the average and return
}
