Description
Objectives : Use the online programming Repl.IT that is used for tutorials and to refresh the programming knowledge you have learnt in IT1010 – Introduction to Programming Environments
Exercise 0
Follow the Instructions given in the document Instructions in using Repl.IT to setup an account and start the first Tutorial.
Once you have completed the steps you should see the following screen. You can tryout the 4 questions of the Tutorial. The questions are called Assignments in Repl.IT
Use the Editor to try out the program and you can run your program using the run button. Once you are satisfied with your solution you can submit your solution
Exercise 1 – Calculations
Write a C program to input marks of two subjects. Calculate and print the average of the two marks.
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
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
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;
}
