Question

Write a program to implement the following steps.

(1) In your main( ) function, declare an array to hold 10 integers.

(2) From main( ), call a function named initarray to initialize your array - read a group of

integers from user input into your own function. Note the array should be visible in the main( )

function.

(3) From main( ), call a function named average to calculate the average of all integers in the

array you declared in the main( ) and return the average back to the main( ) function and assign

it to a variable named avg.

(4) From main( ), call a function named maxval to find the maximum from all integers in the

array you declared in the main( ) and return it back to the main( ) function and assign it to a

variable named max.

(5) In the main( ) function, use the formula y = avg + max to calculate y and print it out.

Explanation / Answer

#include <stdio.h>

void initarray(int data[], int len)

{

int i;

for (i = 0; i < len; i++)

{

printf("Enter integer %d: ", i+1);

scanf("%d", &data[i]);

}

}

double average(int data[], int len)

{

double sum = 0;

int i;

for (i = 0; i < len; i++)

sum += data[i];

return sum / len;

}

int maxval(int data[], int len)

{

int m = 0;

int i;

for (i = 1; i < len; i++)

if (data[i] > data[m])

m = i;

return data[m];

}

int main()

{

double avg;

int max;

double y;

int data[10];

initarray(data, 10);

avg = average(data, 10);

max = maxval(data, 10);

y = avg + max;

printf("y = %f ", y);

return 0;

}
