Section 4.10 The char Datatype
So far we have only stored integer numbers in variables.
You can also store letters or symbols in variables (in computer speak these are called
characters ).
The datatype to store a character is called
char, the format specifier is
%c
Activity 4.8 . printf Practice.
Write a program that prints out “ENGS 20” using the following
printf() statement:
printf("%c%c%cS 20\n", letter1, letter2, letter3);
Please do not make any changes to the
printf statement since the autograder will not function correctly if you do.
Reading characters from the user input. You can use
scanf() to read a character from the user input:
Investigate 4.9 .
What do you think would happen if you tried to use the
scanf() function to read a character, but you use the format specifier for an integer-type variable,
%d? Will it work or fail?
Hint .
Take your best guess, and then feel free to try it out in the code window above
