How to Print Percentage(%) in C language
on 10 June 2011
My friend was so proud of his C programming skills. So to bring him down to earth I just asked him a simple question about Printing Special Characters in C Language. I asked him to write a C code to print percentage symbol. He said what is a big deal in that!
He started writing code in Dev C++ and I was shocked to see his program:
void main() { printf("%"); getch(); }
Lol, compiler showed errors... He did much things like using escape sequence backslash(\) before % to print the percentage sign but all was in vain. At last he succeeded after about an hour!(After referring to a book and ASCII code table) This is the C code he programmed to print the percent special character:
printf("%c", 37);
But this method uses the ASCII code. This is not at all a good method to print it. I will show you a very simple method to print a % symbol which is as follows:
Just use a second percent sign to escape the percent sign!
printf("100%%\n"); // print 100% printf("%%"); // print a percent sign
So that was a simple method for which C language experts would scratch their head..
