Explain C Program Step By Step

The C Program Can Be Explained Using Simple Program. Because, Understand Every One Way Of Learning in C Program & also Explain  comments where do use in c program.

Then above the Symbol  //. Using For C Program Explain time. ( Good Way Understand ). Now , Comments also Be Used Explain Symbols in c program  /* sum text */ .
