Description

This example is to demonstrate printing "Hello World!" to the command line. The printf statement can be very useful for debugging.

Examples

%c is used to print characters

// initialize some characters
char x = 'a';
char y = 'b';
char z = 'c'

// print characters to terminal
printf("characters: %c,%c,%c",x,y,z); // would print 'characters: a,b,c'


%d is used to print integers

// initialize integer with value 42
int x = 42;

printf("The answer is %d",x); // would print 'The answer is 42'


%f is used to print floating point numbers

// initialize pie with value 3.14
float pie = 3.14;

printf("pie = %f ",pie); // would print 'p = 3.14'
