在C中从二进制转换为char [英] Convert from a binary to char in C

问题描述

我对如何从二进制值转换为c中的char感到困惑.

I'm flummoxed by how to convert from a binary value to a char in c.

例如，假设我有01010110，并希望从中打印相应的字母"V".我该怎么做呢?

For example, let's say I have 01010110 and want to print the corresponding letter 'V' from that. How do I do this?

感谢您的帮助！

推荐答案

#include <stdio.h>
#include <stdlib.h>
int main(void)
{
    char *data = "01010110";
    char c = strtol(data, 0, 2);
    printf("%s = %c = %d = 0x%.2X\n", data, c, c, c);
    return(0);
}

输出:

01010110 = V = 86 = 0x56

参考:

• strtol()
• 正确使用strtol()
