OK I'm trying to have a simple loop which keeps on printing each number from 1,2,... on a different line and it keeps on doing so until the user enters 'e'.
e.g
for(i=0;i<=9999999999;i++)
{
printf("%d\n",i);
}

It does not take any input from user and keeps on printing but as soon as user presses e the program exits.Any clue how to go about this.

[haru31773]

so it should continue printing until the user presses E?

Use the following program for printing the integer value unless press E or e. This example will help for your requirement.

#include<stdio.h>
#include<stdlib.h>
main()
{
long i;
char c;
for(i=0;i<=99999;i++)
{
printf("%d",i);
c=getchar();
if(c == 'e' || c == 'E')
{
        break;
}
continue;
}
}

with getchar you stop the execution of the program until the user press enter.
certainly not what he wants.

And no this is not a simple program.
There is not an easy way to do it(especially platform independent).

You need thread or process creation and some signal stuff.

Create a child process which will print the numbers and the parent process will take user input.

Well this doesn't exactly help because the program does not continue printing numbers and it waits for a user input after each number is printed.

Yup exactly guys could any one help me with this.How to go about it.

[virxen]

in which operation system?

[thapchi]

Well the main thing u r missing is

Scanf

where will user enter?
