这是我的示例程序
void first_call();
void second_call();
int main()
{
char *str[]={"We will teach you how to...",
"Move a mountain",
"Level a building",
"Erase the past",
"Make a million",
"...all through C!"};
first_call(str);
return 0;
}
str传递给" first_call()" 现在我想要打印字符' i'来自" mountain"在第二个字符串。
void first_call(char **str)
{
printf("%s",str[1]); //to print second string,working
printf("%c",*(&str[1]+13)); //to print 'i' form second string
//but not working
second_call(&(&str[1]+13)); //to pass address of address of element of string
//not working,and giving error
}
我还想在second_call()中传递该特定地址。
void second_call(char ***s_element)
{
printf("\n%c",**s_element); //not working
}
我应该怎么做。
答案 0 :(得分:0)
改变这个:
printf("%c",*(&str[1]+13));
到此:
printf("%c", *(str[1] + 13));
