自动执行C程序的用户输入

Question

I am planing to make a C program using array of structures which takes input as strings ie, name of movie and genre(4 different genres):

struct movie
   {
      char name[30];
      char genre[4][10];
   }m[30];

void main()
{
   int i,j;
   for(i=0;i<30;++i)
   {
      scanf("%s",m[i].name);                     //Removing gets
      for(j=0;j<4;++j)
      {
          scanf("%s",m[i].genre[j]);             //Removing gets
      }
   }
}

I want to automate the user input of the program from a pre-defined source eg a text file, so that I don't have to insert all the input manually. Is there a script(python/bash) to do this or any other method that can make my job easier for 100s of input.

The reason behind using the C program is to store the inputs in a file for future use.

Answer 1

Write it to accept input from the keyboard. Then use input redirection:

myprogram.out < SampleTestData.txt

Uses the SampleTestData.txt file as if it were keyboard input.
