#include <stdio.h>
#include <string.h>
int main()
{char s1[200],s2[100];
gets(s1);
gets(s2);
strcat(s1,s2);
puts(s1);
return 0;
}
#inclde<string.h>里面的 strcat函数
头文件：#include <string.h>
定义函数：char *strcat(char *dest, const char *src);
函数说明：strcat()会将参数src 字符串拷贝到参数dest 所指的字符串尾。第一个参数dest 要有足够的空间来容纳要拷贝的字符串。
返回值：返回参数dest 的字符串起始地址。
范例 #include <string.h>
main(){
char a[30] = "string(1)";
char b[] = "string(2)";
printf("before strcat() : %s\n", a);
printf("after strcat() : %s\n", strcat(a, b));
}
执行结果：
before strcat() : string(1)
after strcat() : string(1)string(2)
