Question

怎么把people republic of 和china 用c语言连起来，我想了好半天，求解答

Answer 1

stract，头文件中的函数，用于将两个char类型数组相连，结果放在dest中，并返回拼接后的dest和src。

#include <stdio.h>
#include <stdlib.h>
    char *
    Strcat(char *arr1, char *arr2)
{
    char *tempt = arr1;
    while (*arr1 != '\0')
    {
        arr1++;
    }
    while (*arr2 != '\0')
    {
        *arr1 = *arr2;
        arr1++;
        arr2++;
    }
    *arr1 = '\0';
    return tempt;
}
int main()
{
    char a[20] = "hello";
    char b[20] = ",everyOne!";
    printf("%s", Strcat(a, b));
    system("pause");
    return 0;
}
