A lab guide for c programming course at international university. It covers three exercises: determining if a year is a leap year, identifying triangle types based on sides, and calculating circle properties. The exercises involve writing c programs using input/output statements, arithmetic, relational, and logical operators, and problem-solving techniques.

Students are required to review the theory of the topics before the lab time.
Exercise 1 Write a C program to determines whether an input number is even or odd. Output: Input an integer: 15 15 is an odd integer #include <stdio.h> int main() { int a; int b; scanf("%d",&a) ; b= a%2; if(b==0) printf ("%d is an the even interger \n",a);
printf("%d is not a leap year.\n", a); // Print a message indicating that ‘a’is not a leap year. else if ((a % 4) == 0) // Check if ‘a’is divisible by 4 with no remainder. printf("%d is a leap year.\n", a); // Print a message indicating that ‘a’is a leap year. else printf("%d is not a leap year \n", a); // Print a message indicating that ‘a’is not a leap year. } Exercise 3 Write a C program to identify whether a triangle is Equilateral, Isosceles or Scalene based on the given sides. For Example: Output: Input three sides of triangle: 30 30 50 This is an isosceles triangle. # include <stdio.h> int main() { int a,b,c; printf ("Input three sides of triangle:"); scanf ("%d",&a); scanf ("%d",&b); scanf ("%d",&c); if (a==b==c) printf("This is an Equilateral triangle\n");// the triangle is Equilateral when a=b=c. else if (a==b) printf("This is an Isosceles triangle\n");// the triangle is Isosceles when a=b. else if (a==c) printf("This is an Isosceles triangle\n");// the triangle is Isosceles when a=c.
else if (b==c) printf("This is an Isosceles triangle\n");// the triangle is Isosceles when b=c. if ((a^2)==(b^2)+(c^2)) printf("This is an Scalene triangle\n");// the triangle is Scalen. else if ((b^2)==(a^2)+(c^2)) printf("This is an Scalene triangle\n"); else if ((c^2)==(b^2)+(a^2)) printf("This is an Scalene triangle\n"); return 0; } Exercise 4 Write a C program to input radius of a circle from user and find diameter, circumference, and area of the circle. For example: Output: Enter the radius of a circle: 3 Diameter of circle = 6.00 units Circumference of circle = 18.84 units Area of circle = 28.26 sq. units #include <stdio.h> int main() { float radius, diameter, circumference, area; //Input radius of circle from user printf("Enter radius of circle: "); scanf("%f", &radius); // Calculate diameter, circumference and area diameter = 2 * radius; circumference = 2 * 3.14 * radius; area = 3.14 * (radius * radius); //Print all results
printf ("Enter the Values of b :"); scanf ("%f",&b); printf ("Enter the Values of c :"); scanf ("%f",&c); deta=(bb)-4(ac); d=(-b)/(2a);//this is a Values of Only root e=(-b+(sqrt(deta)))/(2a); f=(-b-(sqrt(deta)))/(2a); if (deta<0) printf ("The equation has no root");//Consider the conditions of the equation. else if (deta==0) printf("%fThe equation has only root:",d); else if(deta>0) { printf ("The roots of equation are:\n"); printf ("First root:%f \n", e); printf ("Second root:%f \n", f); } return 0; } Exercise 6 Write a C program that calculate the total payment of Taxi service, in which:
#include <stdio.h> int main() { int cost,distance; printf ("Enter total distance in km:"); scanf ("%d",&distance);//input distance. // Calculate total cost. if (distance==0) cost=0;// when we do not use taxi. if (distance<=30) cost= 5+ 3(distance-1);//when the distane < 30 else cost = 5+(293)+2*(distance-30);// when the distane > printf ("\n The total cost that a passenger has to pay: %d",cost ); return 0; } Exercise 7 Write a C program to read student’s name, student’s ID and marks of three subjects (Literature, Math and English) and calculate the total, average and division. Division is defined as follows: Average ≥ 60: A 48 ≤ Average ¿60: B 36 ≤ Average ¿48: Pass Average ¿36: Fail For Example Output: Input the Name of the Student: Kien Input the No of the student: 10 Input the marks of Literature, Math and English: 50 80 70
per = total / 3.0; // Calculate percentage. if (per >= 60) // Check if percentage is greater than or equal to 60. strcpy(div, "First"); // Assign division as "First" if condition is true. else if (per < 60 && per >= 48) // Check if percentage is between 48 and 60. strcpy(div, "Second"); // Assign division as "Second" if condition is true. else if (per < 48 && per >= 36) // Check if percentage is between 36 and 48. strcpy(div, "Pass"); // Assign division as "Pass" if condition is true. else // If none of the above conditions are met. strcpy(div, "Fail"); // Assign division as "Fail". printf("\nRoll No : %d\nName of Student : %s\n", rl, nm); // Print roll number and name. printf("Marks in Physics : %d\nMarks in Chemistry : %d\nMarks in Computer Application : %d\n", phy, che, ca); // Print marks in each subject. printf("Total Marks = %d\nPercentage = %5.2f\nDivision = %s\n", total, per, div); // Print total marks, percentage, and division. } THE END
