printf unsigned long long int

printf is a C function used to print formatted output to the console or a file. unsigned long long int is a data type in C used to represent integers that are at least 64 bits in size and can only hold non-negative values.

To print an unsigned long long int value, you can use the following format specifier in printf:

%llu

For example:

unsigned long long int num = 18446744073709551615ULL;
printf("The value of num is: %llu\n", num);

Output:
The value of num is: 18446744073709551615

unsigned long 和 unsigned int

unsigned long和unsigned int是C语言中的数据类型修饰符。它们与signed long和signed int的区别在于是否带有符号。

unsigned long是无符号长整型，它可以存储非负整数，范围从0到4294967295（2^32-1）。

unsigned int是无符号整型，它也可以存储非负整数，范围从0到4294967295（2^32-1）。

这两个数据类型修饰符的主要区别在于它们的范围和存储空间大小。unsigned long的范围和存储空间大小比unsigned int更大。

以下是一个演示示例：

#include <stdio.h>

int main() {
    unsigned long ul = 4294967295;
    unsigned int ui = 4294967295;

    printf("Unsigned long: %lu\n", ul); // 输出：Unsigned long: 4294967295
    printf("Unsigned int: %u\n", ui); // 输出：Unsigned int: 4294967295

    return 0;
}

c语言printf函数long unsigned int怎么输出

使用 `%lu` 格式控制符来输出 `long unsigned int` 类型的数据。例如：

unsigned long num = 4294967295UL;
printf("num = %lu\n", num);

输出结果为：

num = 4294967295
