strcmp1.cpp

c语言教程源码

//这个程序在本书所带软盘中。文件名为STRCMP1.CPP
//这个程序演示字符串比较函数strcmp()的各种比较结果。

#include <iostream.h>
#include <string.h>

void main(void)
{
	char string1[] = "computer";
	char string2[] = "computing";
	char string3[20] = "computer";
	char string4[] = "Computer";
	char *string5 = "computre";

	cout << "strcmp(string1, string2) = " << strcmp(string1, string2) << endl;
	cout << "strcmp(string1, string3) = " << strcmp(string1, string3) << endl;
	cout << "strcmp(string1, string4) = " << strcmp(string1, string4) << endl;
	cout << "strcmp(string1, string5) = " << strcmp(string1, string5) << endl;
}

/*程序运行后的结果为：
strcmp(string1, string2) = -4
strcmp(string1, string3) = 0
strcmp(string1, string4) = 32
strcmp(string1, string5) = -13
