Question

C programming

Rewrite the following code replacing the else-if construct with a switch statement. Make sure you test your code.

Supplied code

#include <stdio.h>

int main(void)

{

char ch;

int countA = 0;

int countE = 0;

int countI = 0;

printf("Enter in a letter A, E, or I.\n");

scanf(" %c", &ch);

//Replace the following block with your switch

if(ch == 'E' || ch == 'e')

countE++;

else if(ch == 'A' || ch == 'a')

countA++;

else if(ch == 'I' || ch == 'i')

countI++;

else

printf("Error, %c is not an A, E or I.\n", ch);

//end of your switch

return 0;

}//end main
