使用printf格式化不均匀的列表

#include <stdio.h>

int main() {
    int num1 = 123;
    int num2 = 45678;
    int num3 = 7890123;

    printf("%-10s %10s\n", "Number", "Value");
    printf("%-10s %10d\n", "num1", num1);
    printf("%-10s %10d\n", "num2", num2);
    printf("%-10s %10d\n", "num3", num3);

    return 0;
}

Number           Value
num1               123
num2             45678
num3           7890123
