Write a program using user defined function that will display all prime integers that the user enters

Question

#include <stdio.h>
int checkPrime(int number);
int main() {
int m[6];
int k;
printf("Enter 6 numbers\n");

for(k=0;k<6;k++){
scanf("%d", &m[k]);
}
for(k=0;k<6;k++){
printf("%d\n", checkPrime(m[k]));
}

return 0;
}

int checkPrime(int number)
{
int count = 0;
for(int i=2; i<=number/2; i++)
{
if(number%i == 0)
{
count=1;
break;
}
}
if(number == 1) {
count = 1;
return number;
}
}

the code has an error please help out

Answer 1

Lets assume input is 3,4,5,6,7,8

These get place in m

printf("%d\n", checkPrime(m[k]));
This line requires a return value of int from int checkPrime(int number)

First iteration:

int checkPrime(3)
{

int count = 0;

for(int i=2; i<=number/2; i++)
{
if(number%i == 0)
{
count=1;
break;
}
}

if(number == 1) {
count = 1;
return number;
}

}

Processing:
2 is greater than 3 / 2 in integer math..
3 does not equal 1..
the function has no return value creates an errror.

Your function should printf if checkprime is true.

rewrite it in a:

if(checkPrime(int number) == someValueYouChooseToReturn) printf("%d\n", m[k]);
