programming */

Short comments in the same line can be written after //Example: printf(“\n"); //insert new line

Compilation Errors

If there are any errors in your program, the compiler will indicate the line number of the error along with an explanation.

See the bottom window to check the compiler’s output!!

/* Write your name, student number and comments here */#include <stdio.h>Void main(void){ Printf(“Welcome to”);Printf(“GE 208 Lab!\n”); Printf(“This line should give a beep!\a\n”); Printf(“This\tline\tis tabbed\n”); Printf(“This” “is” “another” “printf\n”); Printf(“One\”); Printf(“line\n”);Printf(“This should not appear\r where did the text go?\n”);Printf(“Where is the ‘C’ in ABC\b?\n”);Printf(“If you want to print \\, \\n, \” or %% on the screen\n”);}
