  1. POHow to test my program against an input test case file
    text
    copied!<p>I was participating in some coding contests and luckily my code also ran. However my solution was not expected because i was wrong with the pattern of taking input. </p> <hr> <p>The question involved taking in an integer as an input and performing some operation and returning a different or same integer. I do not have any problem with the program, I just don't know how to code so as to take inputs like this</p> <hr> <pre><code>Input The input will contain several test cases (not more than 10). Each test case is a single line with a number n, 0 &lt;= n &lt;= 1 000 000 000. It is the number given as input. Output For each test case output a single line, containing the integer returned. </code></pre> <hr> <pre><code>Example Input: 12 2 Output: 13 2 </code></pre> <hr> <p>My code is </p> <hr> <pre><code>#include &lt;stdio.h&gt; int functionReturningInteger(int n) { // implementation ........ return num; } int main(void) { int number; //printf("Enter the number: "); scanf("%d",&amp;number); printf(functionReturningInteger(number)); return 0; </code></pre> <p>}</p> <hr> <p>How am i supposed to know how many inputs they will give ( although they do provide a maximum limit). And if i use an array to store these inputs whose size is equal to the maximum limit, how do i check the size of an integer array in c ?</p> <hr> <p>I will appreciate anybody helping out with a small piece of code. Also if am able to test it against an input test file and generate an "output.txt" (output file). I already have the desired output file "des.txt". Then how can i match whether both the files are same or not ?</p>
