C programming; Lesson 4:Print on screen
We use the printf function to print on the screen.
If we only want to print a text message the form of the function is:
printf ("string of characters to be printed on the screen");
If we want to print a value stored in a particular variable, the form of the function is:
printf ("list_format", variable_lists);
In the format list, we list the variable format we want to print. The format of the variable consists of the character% and type of format:
format meaning %c Load one character %d Load integer %f Load real number %s Load string %u Print decimal number unsigned
Example of printing only a value of a variable :
int a = 5;
printf ("%d", a);
Example of text output and variable value:
int nm_stud = 7;
float average = 4.15;
printf ("The number of students is%d, and their average is%f", nm_stud, average);
