Question

Write a C program which takes 5 numbers from the user. Write a switch case to find out
how many numbers are even

Answer 1

#include<stdio.h>
void main()
{
int a[5],i,count_even=0,count_odd=0;
printf("\n\nEnter any five numbers: ");
for(i=0;i<5;i++)
{
scanf("%d",&a[i]); // reading five numbers from the keyboard
}
for(i=0;i<5;i++)
{
switch(a[i]%2) // logic begins ere
{
case 0: // case matches when switch variable remainder is 0
   count_even++;
   break;
case 1: // case matches when switch variable remainder is 1
   count_odd++;
}
}
printf("Number of even numbers in the given list of numbers are %d",count_even);
printf("\nNumber of odd numbers in the given list of numbers are %d",count_odd);
}
