c语言long的格式化输出

在C语言中，可以使用以下格式化输出符号来输出long类型数据：

- %ld：用于输出10进制的long整数
- %lo：用于输出8进制的long整数
- %lx或%X：用于输出16进制的long整数，其中%lx输出小写字母，%lX输出大写字母

下面是一个示例代码，演示如何使用这些格式化输出符号输出long类型数据：

#include <stdio.h>

int main() {
    long num1 = 1234567890;
    long num2 = 0777;
    long num3 = 0xABCDEF;

    printf("num1 in decimal: %ld\n", num1);
    printf("num1 in octal: %lo\n", num1);
    printf("num1 in hexadecimal (lowercase): %lx\n", num1);
    printf("num1 in hexadecimal (uppercase): %lX\n", num1);

    printf("num2 in decimal: %ld\n", num2);
    printf("num2 in octal: %lo\n", num2);
    printf("num2 in hexadecimal (lowercase): %lx\n", num2);
    printf("num2 in hexadecimal (uppercase): %lX\n", num2);

    printf("num3 in decimal: %ld\n", num3);
    printf("num3 in octal: %lo\n", num3);
    printf("num3 in hexadecimal (lowercase): %lx\n", num3);
    printf("num3 in hexadecimal (uppercase): %lX\n", num3);

    return 0;
}

输出结果如下：

num1 in decimal: 1234567890
num1 in octal: 11145401322
num1 in hexadecimal (lowercase): 499602D2
num1 in hexadecimal (uppercase): 499602D2
num2 in decimal: 511
num2 in octal: 777
num2 in hexadecimal (lowercase): 1FF
num2 in hexadecimal (uppercase): 1FF
num3 in decimal: 11259375
num3 in octal: 52713157
num3 in hexadecimal (lowercase): ABCDEF
num3 in hexadecimal (uppercase): ABCDEF
