Declare, Initialize & Use Variables | C Programming | Kovolff

To compile C programs in the terminal gcc -o {target_name] [source_name] Upon compiling an executable(.exe) file is created, called whatever you input as [target_name]. To run this file in the terminal [target_name].exe Variables can be seen as containers that hold values. These values can change throughout the running of the program. To declare a variable in C, follow this general form type name; i.e. int user_age; Here we declared the variable user_age which is an integer of type int. C is a statically typed language, meaning that the type of each variable must be explicitly declared upon creation. i.e. int user_age = 23; Here we not only declared the variable user_age of type int, but also initialized to the value of 23 To include the value of your variables into your outputs i.e. printf(“your age is %d years old”, user_age); %d is a placeholder for the value of user_age For every placeholder you insert in your string, you need a variable that is passed to printf() along with the string #c #programming #variables
