    For some reason, my program keeps a newline in an integer

    This is my program.
    Code:
    #include <stdio.h>
    int main ()
    {
        int num1, num2;
        int num3;
        char letter;
        /* part a */
        scanf("%d", &num1);
        scanf("%d",&num2);
        printf("%d\n", num1/num2);
        printf("%d\n", num1 % num2);
        printf("%.2f\n", (float)num1/num2);
        /* part b */
        scanf("%c", &letter);
        printf("%d\n", letter);
        printf("%c\n", letter+32);
        /* part c */
        scanf("\n %d", &num3);
        printf("%d\n", num3);
    }
    It does some really crazy things. The output I get on part c is something like -854892179.
    Just input something like "3" "2" "a" and watch it all go to heck.

    and when I look at debugger windows I see "letter" contains a newline, but I can't figure out why. Would appreciate your help.

    try putting a space before the %c when you scan into letter
    Ex.)
    Code:
    scanf(" %c", &letter);
