如何在C语言中比较两个字符串?帮我一下,我是初学者@@
char *str1 = "hello";
char *str2 = "world";
//compare str1 and str2 ?
char *str1 = "hello";
char *str2 = "world";
//compare str1 and str2 ?
您可能希望使用strcmp
函数:
#include <stdio.h>
#include <string.h>
int main(int argc, char **argv)
{
int v;
const char *str1 = "hello";
const char *str2 = "world";
v = strcmp(str1, str2);
if (v < 0)
printf("'%s' is less than '%s'.\n", str1, str2);
else if (v == 0)
printf("'%s' equals '%s'.\n", str1, str2);
else if (v > 0)
printf("'%s' is greater than '%s'.\n", str1, str2);
return 0;
}
结果:
'hello' is less than 'world'.
if ( strcmp( str1, str2 ) == 0 )
