Tutorial 01

Objectives : Revise writing C Programs

This week we will revisit writing C programs. In IT1050 the programming language you will use C++ is based on the C language and you have to use your C knowledge to write C++ programs

Exercise 1 - Calculations

Write a C program to input marks of two subjects. Calculate and print the average of the two marks.

Program File - Tute01.c

Exercise 2 - Selection

Write a program to calculate the amount to be paid for a rented vehicle.

Input the distance the van has travelled
The first 30 km is at a rate of 50/= per km.
The remaining distance is calculated at the rate of 40/= per km.

e.g.

Distance -> 20
Amount = 20 x 50 = 1000


Distance -> 50
Amount = 30 x 50 + (50-30) x 40 = 2300

Program File - Tute02.c

Exercise 3 - Repetition

Write a C program to calculate the sum of the numbers from 1 to n. Where n is a keyboard input.

e.g.

n -> 100
sum = 1+2+3+....+ 99+100 = 5050

n -> 1-
sum = 1+2+3+...+10 = 55

Program File - Tute03.c

Exercise 4 - Functions

Implement the three functions minimum(), maximum() and multiply() below the main() function.

Do not change the code given in the main() function when you are implementing your solution.

int main() {
   int no1, no2;
   printf("Enter a value for no 1 : ");
   scanf("%d", &no1);
   printf("Enter a value for no 2 : ");
   scanf("%d", &no2);
   printf("%d ", minimum(no1, no2));
   printf("%d ", maximum(no1, no2));
   printf("%d ", multiply(no1, no2));
   return 0;
}
