Strlen(...)

Code:

---

#include <iostream.h>

int main()
{
char x;

while(strlen(x)) < 8
{
cin >> x;
}
return 0;
}

---

This code should allow the user to type in a word in x, but should automatically go on to the next operation when the length of x reaches 8. I can't compile it due to an error on the WHILE line, how can I solve it ?

> while(strlen(x)) < 8

while(strlen(x) < 8 )

Code:

---

char text[100];
do {
    cin.width(100);
    cin >> text;
}while(strlen(text) < 8);

---

Code:

---

#include <iostream.h>

int main()
{
char x;

while(strlen(x) < 8)
{
cin >> x;
}
return 0;
}

7 C:\3.cpp
passing `char' to argument 1 of `strlen(const char *)' lacks a cast


Damn...

strlen expects char*, not char

This might do what you are looking for:

Code:

---

char str[9];
for(int i = 0; i < 8; ++i)
    cin >> str[i];
str[8] = '\0';

Thanks... But then how do you use Strlen ?

In the above example, you could use strlen(str) since str is a char*. You just can't use it on a char (since its length is always 1).
