strchr()函数
原型:extern char *strchr(const char *s,char c);
头文件:#include <string.h>
功能:查找字符串s中首次出现字符c的位置
说明:返回首次出现c的位置的指针,如果s中不存在c则返回NULL。
举例1:(在Visual C++ 6.0中运行通过)
#include <string.h>
#include <stdio.h>
int main(void)
{
char string[15];
char *ptr, c = 'r';
strcpy(string, "This is a string");
ptr = strchr(string, c);
if (ptr)
printf("The character %c is at position: %d\n", c,
ptr-string);
else
printf("The character was not found\n");
return 0;
}
运行结果:The character r is at position: 12Press any key to
continue
举例2:
// strchr.c
#include <stdio.h>
#include <string.h>
main()
{
char temp[32];
memset(temp,0,sizeof(temp));
strcpy(temp,"Golden Global View");
char *s = temp;
char *p,c='v';
p=strchr(s,c);
if(p)
printf("%s",p);
else
printf("Not Found!");
return 0;
}
运行结果:Not Found!Press any key to continue
