Thread: Dumb Question: What is sscanf?

Please don't bash me. I really don't understand it. I know how to use sprintf and stuff but sscanf?

On a tutorial is says:

.....sscanf is just like scanf, only it gets the input from a string

Doesn't ssprint do the same thing?

Code:

#include <iostream>
#include <cstdio>
#include <cstdlib>

using std::cin;

int main( int argc, char *argv[] )
{
  char Buffer[255];
  char Name[255];


  printf("Input your name: ");
  scanf( "%s", Name );

  sprintf( Buffer, "Your Name: %s", Name );
  printf("%s", Buffer);


  cin.get();
  return 0;
}

No. sprintf() takes a bunch of values and creates a string, like
-- printf() to screen output
-- sprintf() to a string buffer

sscanf() takes a string and breaks it up into values, like
-- scanf() input from keyboard
-- sscanf() input from a string buffer

am I the only one who notices that he is using C++ libraries and using C functions??

Well I guess its alright cuz of CSTDLIB

but please just do

Code:

#include <stdlib.h>

and if ur going to program in C, stay away from C++ stuff like cin

Code:

int sprintf( char *buffer, const char *format [, argument] ... );

Parameters:

buffer

Storage location for output

format

Format-control string

argument

Optional arguments
________________________

sprintf takes a string buffer and allows one to change formatted text into a string to be placed in that buffer.

Ex:

Code:

char myBuffer[256];
sprintf(myBuffer,"this buffer is called %s and is %d characters big","myBuffer",256);
