Main arguments

[nk28]

Basically I want to take a long string as an input whose size i don't know in C.
I want to do later functions on it.

Can anyone suggest any ways to do it.

Also I wanted to know can i do the same using main argument argv?????

Just opass your string as a char*. You don't need to know the length as you can call strlen() to find that out.

argv of main() is a pointer to an array of char*. So qall you need do is place your string on the command line. You increment argc when yo do this.

Any text on C will jave this information.

Thanxx for the reply but i do not want to know how to pass the string in the function......

What i want to know is how to take input of a string whose size has to be variable and i don't know it.............
Any other method than main(char *argv[])

Why can't you use strlen()?

It doesn't matter whether it's an argument to main() or not sionce main() is just a function.

void func(char* str)
{
   unsigned int length = strlen(str);
}
