6、字符串操作函数--strchr()

strchr() 字符查找

void test06()
{
char str[] = “hello world”;
printf("%s\n", str);
//需求：找出所有的’l’并将’l’替换成’*’
char ret = NULL;
while((ret=strchr(str,‘l’)) && (ret=’’) );
/
while (1)
{
char ret = strchr(str, ‘l’);
if (ret != NULL)
{
//ret就是’l’的地址
ret = '’;
}
else
{
break;
}
}/
printf("%s\n", str);
}
