在scanf（）中单独输入？

Question

I want to separate a 5 digit number taken in through scanf() into three different variables. The first variable should have the first digit, the second should have the second 2 digits, and the third should have the last 2 digits.

I was thinking of something like this:

int num1;
int num2;
int num3;
scanf(%1d%2d%2d, &num1, &num2, &num3);

However, this doesn't work: it assigns the last two digits to every variable.

Is there any way to do this without separating the number after scanning in all 5 digits?

Answer 1

Change this:

scanf(%1d%2d%2d, &num1, &num2, &num3);

to this:

scanf("%1d%2d%2d", &num1, &num2, &num3);

since you forgot to use the double quotes.

See this example:

#include <stdio.h>

int main(void) {
    int num1, num2, num3;
    scanf("%1d%2d%2d", &num1, &num2, &num3);
    printf("%d %d %d\n", num1 ,num2, num3);
    return 0;
}

Output:

> 12345
1 23 45
