Hi,

I make a simple c file which takes input from user and then display it. I am trying to make a bash script in which i predefined those input and then run the c program inside bash and the c program takes the input which i have defined (i.e. user don't need to enter the input)

Here is the code.

#include<stdio.h>

void main()

{

char ch;

int num;

printf("Enter a single character:\n");

scanf("%c", &ch);

printf("Enter any number:\n");

scanf("%d", &num);



printf("You type charachter %c\n", ch);

printf("You type number %d\n", num);

}

#!/bin/bash



ch=s



num=2



./test < $ch $num

When i run the bash script it don't take the input values of ch and num. then i find on Google to use | so i tried ./test | $ch $num but didn't work

Please help me.

Thank you
