The following functions should return the sum, average, and standard deviation of an array of integers. What's wrong with this code? (unfortunately I cannot test it myself right now). This is my first program in C, very exciting, hope you can help me. Thanks!
Code:#include <stdio.h> #include <stdlib.h> #include <math.h> int main(int argc, char **argv) { int sum(int *numbers, unsigned short count){ int i; int sum = 0; for(i=0, i < count, i ++) { sum = sum + numbers[i]; } return sum; } double average(int *numbers, unsigned short count){ float avg; int sum; sum = sum(numbers, count); avg = sum/count; return avg; } double sd(int *numbers, unsigned short count){ float avg; int i; float var; int sum = 0; avg = average(numbers, count); for(i = 0, i < count, i ++) { sum = sum + pow((numbers[i] - avg), 2); } var = sum/count; return sqrt(var); } int numbers[] = {15, 0, -3, 7, 27743, 6, 8, 1, -5732, 1, 9}; printf("The sum is %d\n", sum(numbers, 11)); printf("The average is %7.2f\n", average(numbers, 11)); printf("The standard deviation is %7.2f\n", sd(numbers, 11)); return 0; } }
