Scanning character and integer in single scanf multiple times

Question

int main()
{
int a,i;
 char b;
for(i=0;i<3;i++)
 scanf("%c %d",&a,&b);

}

The program only scans twice (each for char and int) and then terminates.

OUTPUT

r

3

4

t

Now program is terminating rather than scanning two more times(one char and one int)

Answer 1

scanf(" %c %d",&a,&b);

Answer 2

The program scan twice because you tell him to with i < 3 . Change the 3 to 5 to scan 4 times.
