The First C Program
To start with the first program lets write what we actually want to instruct the Computer Processor to do:
a. I want the Computer Processor to display character that I type.
b. I want it to be displayed on the Computer Monitor Screen.
c. I will type the character on my keyboard and I want the Computer Processor to read what I typed.
In order to do all of this certainly we need a complete Computer Set System and obviously by reading this tutorial you already got everything.
Lets write the program on the C Compiler.
Open the C Compiler and open new file to write C program.
Write the program and save it as First.c.
#include <stdio.h>
int main()
{
printf("Processor please display this character!\n");
return 0;
}
Compile the C program as shown below:
Run the program and the output is shown below:
When executed, this program instructs the computer to print out the line - Processor please display this character! -- then the program quits. To make the program display the output until we type any character just add C code getchar() inside the program.
#include <stdio.h>
int main()
{
printf("Processor please display this character!\n");
getchar(); //output will wait until user type any
//charr on the keyboard
return 0;
}
