This document provides information about a computing fundamentals course taught by Dr. Muhammad Yousaf Hamza. It includes details about the instructor's qualifications, course contents covering basic computer components and programming in C, recommended textbooks, and objectives of the course which are to learn computer fundamentals and the C programming language. It also presents sample C code for a basic program that calculates the sum and difference of two integers as an example of the first program students will write in the course.

6. Objective of the Course
• To learn computer fundamentals
• To learn C language.
Why Learn C?
• C is the base language of most of the other
programming languages.
• To be a Good Programmer, one must know
fundamentals of C programming language.
• Simulations ----- lets us apply maths to the
real world.

8. Let us Write First C Program
Dr. Muhammad Yousaf Hamza

9. Approach To Our First C Program
x = 5;
y = 7;
z = x + y;
x, y and z are integer variables
Dr. Muhammad Yousaf Hamza

10. Data Types
• Integer variables (int)
For example:
– Number of students
– Number of tables
• Floating point variables (float)
For quantities which may contain decimal point
such as distance, area, and temperature.
• Character variables (char)
At this stage, we will focus only on integers.
Dr. Muhammad Yousaf Hamza

11. Approach To Our First C Program
x = 5;
y = 7;
z = x + y;
x, y and z are integer variables
Dr. Muhammad Yousaf Hamza

12. #include <stdio.h>
int main( )
{
int x, y, z;
x = 5;
y = 7;
z = x + y;
printf(“%d", z);
getchar();
return 0;
}
//Our First C Program
Dr. Muhammad Yousaf Hamza

13. #include <stdio.h>
int main( )
{
int x, y, z;
x = 5;
y = 7;
z = x + y;
printf(“%d", z);
getchar();
return 0;
}
12
//Our First C Program
Dr. Muhammad Yousaf Hamza

14. #include <stdio.h>
int main( )
{
int x, y, z;
x = 5;
y = 7;
z = x + y;
printf(“Sum is %d", z); // Compare it with printf(“%d", z);
getchar();
return 0;
}
Sum is 12
Dr. Muhammad Yousaf Hamza

15. #include <stdio.h>
int main( )
{
int x, y, z, m;
x = 5;
y = 7;
z = x + y;
m = x - y;
printf("Sum is %d", z);
printf("Difference is %d", m);
getchar();
return 0;
}
Sum is 12Difference is -2
Dr. Muhammad Yousaf Hamza

16. #include <stdio.h>
int main( )
{
int x, y, z, m;
x = 5;
y = 7;
z = x + y;
m = x - y;
printf("Sum is %dn", z);
printf("Difference is %d", m);
getchar();
return 0;
}
Sum is 12
Difference is -2
Dr. Muhammad Yousaf Hamza

17. #include <stdio.h>
int main( )
{
int x, y, z, m;
x = 5;
y = 7;
z = x + y;
m = x - y;
printf("Sum is %dnDifference is %d", z, m); // two outputs in
//one printf
getchar();
return 0;
}
What’s output?
