C exercises - conditional statements
1. Write a C code that prompts the user to input three integer values and
find the greatest value of the three values.
Page 3
Introduction to Computing
By: Mr. Iyad Albayouk
Example :
Enter 3 integer vales separated by space: 10 15 20
The greatest value is: 20
2. Write a program that determines a student's grade. The program will
read three scores and determine the grade based on the following rules:
-if the average score >=90% and <=100 =>grade=A
-if the average score >= 70% and <90% => grade=B
-if the average score>=50% and <70% =>grade=C
-if the average score<50%
=>grade=F
3. Write C code to compute the real roots of the equation:
ax+bx+c=0.
The program will prompt the user to input the values of a, b, and c. It then
computes the real roots of the equation based on the following rules :
- if a and b are zero
=> no solution
- if a is zero
=>one root (-c/b )
- if b-4ac is negative =>no roots
- Otherwise
=> two roots
The roots can be computed using the following formula :
Xj=-b+(b²-4ac)?/2a
X2=-b-(b²-4ac)/2a
