I am going to be running a C program from inside a bash script. 

The c program expects inputs from the user. total number of inputs are 7. which are on 7 different lines. for example

```
Please enter input1: 
1
Please enter input2: 
2
Please enter input3:
3

```

so on..
I did some reading up and found out that bash here strings are used for this purpose. So I ran the program, from inside a bash script with the following command

```
./runnable <<< 1 

```

this solves the purpose when the input is required only once...what is the solution when multiple inputs will be required?
