int describes a integer, that if we are including an integer we have to include "int" but why we have to include int at the beginning of the program ??

return 0; This statement terminates the main() function and returns the value 0 to the calling process. The number 0 generally means that our program has successfully executed. Any other number indicates that the program has failed.

Since the code says int main(), you have to return an int. If the program returns the value 0, then the program has no issues. Otherwise, something went wrong.
