Enter two characters: T3
Invalid input
Explanation / Answer
#include<stdio.h>
#include<stdlib.h>
void main()
{
char str[2];
printf(" type 'EX' to exit");
while(1)
{
printf(" enter two characters:");
scanf("%s",&str);
if(str[0]=='M' && str[1]=='1')
printf(" Mathametics Freshman");
else if(str[0]=='M' && str[1]=='2')
printf(" Mathametics Sophomore");
else if(str[0]=='M' && str[1]=='3')
printf(" Mathametics junior");
else if(str[0]=='M' && str[1]=='4')
printf(" Mathametics Senior");
else if(str[0]=='C' && str[1]=='1')
printf(" Computer Science Freshman");
else if(str[0]=='C' && str[1]=='2')
printf(" Computer Science Sophomore");
else if(str[0]=='C' && str[1]=='3')
printf(" Computer Science junior");
else if(str[0]=='C' && str[1]=='4')
printf(" Computer Science Senior");
else if(str[0]=='I' && str[1]=='1')
printf(" Information Technology Freshman");
else if(str[0]=='I' && str[1]=='2')
printf(" Information Technology Sophomore");
else if(str[0]=='I' && str[1]=='3')
printf(" Information Technology junior");
else if(str[0]=='I' && str[1]=='4')
printf(" Information Technology Senior");
else if(str[0]=='E' && str[1]=='X') exit(0);
