Question

Q3)   Write a C program that counts the number of odd numbers with using function count() within the set. The set has only one negative number which determines the end of set.

Answer 1

Program:

#include <stdio.h>

int count(int num[], int size); // Function prototype

int main()

{

int num[100],i=0; // variable declaraiton

printf("Enter numbers in the set(Negative number indicate end of the set:\n");

scanf("%d",&num[i]); // Accept the number

while(num[i]>0)

{

i++; // increment i value

scanf("%d",&num[i]); // Accept the number

}

printf("The number of odd numbers in the set is %d\n",count(num,i)); // calling funvtion and print the return value

return 0;

}

int count(int num[], int size) // Function prototype

{

int odd; // variable declaraiton

for(int i=0;i<size;i++)

{

if(num[i]%2==1) // check number is odd

odd++; // calculate number of odd numbers

}

return odd; // return count of odd numbers

}

Output:
