srinivas reddy replied to hello guys i am new in coding, i want to learn c++ so i started a simple and my firstin Cif you want to learn c++, better learn c first then later c++ easy for freshers. the above code has two mistakes one is you are writing void main() it means nothing to return(just keep return;) if your want use int main() it will return value(i.e return 0; or return (expression)),a nd another is scanf("%d%d\n", &a,&b); \n is used for new line so in scanf it is not necessary ,it is used in printf for cursor into new line.Leave a comment:
