C - equivalent of .NET Console.ReadLine

I need to accomplish the same behavior as .NET Conso开发者_如何学Cle.ReadLine function provides. The program execution should continue when the user pushes enter key.

The following code is not sufficient, as it requires additional input:

printf ("Press Enter to continue");
scanf ("%s",str); 

Any suggestions?


You could use fgets(), like so:

#include <stdio.h>

fgets(buf, sizeof(buf), stdin);


Use the function getchar()


try this:

printf ("Press Enter to continue"); 
scanf(“%[^\n]“,str);


getline is probably better than getchar in most cases. It allows you to capture all of the user's input before the "enter" and is not subject to buffer overflows.

char *buf=NULL;
printf("Press enter to continue: ");
getline(&buf,0,stdin);
// Use the input if you want to
free(buf); // Throw away the input


You can use do while with scanf function.

do{
    scanf("%s",str1);
}while(str1[0] == '\0' || str1[0] == '\r' || str1[0] == '\n');
0
