C Programming Basic Concept
01. Write a C program to compute the perimeter and area of a rectangle with a height of 7 inches and a width of 5 inches.
Expected Output:
The perimeter of the rectangle = 24 inches
Area of the rectangle = 35 square inches
#include <stdio.h> int main() { int height, width, area, primeter; height = 7; width = 5; primeter = 2*(height+width); area = height*width; printf("Perimeter = %d inchies\n", primeter); printf("Area = %d square inchies\n", area); return 0; }
02. Write a C program to compute the perimeter and area of a circle with a given radius.
Expected Output:
Perimeter of the Circle = 37.680000 inches
Area of the Circle = 113.040001 square inches
#include <stdio.h>
int main() {
double radius, perimeter, area, pi;
pi = 3.14159;
radius = 6;
perimeter = 2 * pi * radius;
area = pi * radius * radius;
printf("Perimeter of the Circle = %.6lf inches\n", perimeter);
printf("Area of the Circle = %.6lf square inches\n", area);
return 0; }
03. Write a C program to convert specified days into years, weeks and days.
Note: Ignore leap year.
#include <stdio.h> int main() { int total_days, years, weeks, days; total_days = 1329; years = total_days / 365; weeks = (total_days % 365) / 7; days = total_days - ((years*365)+(weeks*7)); printf("Years: %d\n", years); printf("Weeks: %d\n", weeks); printf("Days: %d\n", days); return 0; }
04. Write a C program that reads two integers and checks whether they are multiplied or not.
Test Data:
Input the first number: 5
Input the second number: 15
Expected Output: Multiplied!
#include <stdio.h>
int main() {
int num_a, num_b;
printf("Input the first number: ");
scanf("%d", &num_a);
printf("Input the second number: ");
scanf("%d", &num_b);
if (num_b % num_a == 0) {
printf("Multiplied!");
} else {
printf("Not multiplied!"); }
return 0; }
05. Write a C program to Check Whether a Number is Positive or Negative or Zero.
Explain the provided program using examples.
#include <stdio.h> int main() { int number; printf("Enter a number: "); scanf("%d", &number); if (number > 0) { printf("%d is positive.\n", number); } else if (number < 0) { printf("%d is negative.\n", number); } else { printf("The number is zero.\n"); } return 0; }
06. Write a C program to Check Leap Year. Demonstrate the provided program using examples.
#include<stdio.h>
int main() {
int year;
printf("Enter any year: ");
scanf("%d",&year);
if(year%400==0){
printf("it's leap year = %d",year);
} else if(year%4==0 && year%100!=0){
printf("it's leap year = %d",year);
} else printf("it's not leap year");
return 0; }
07. Write a C program for Even and Odd number. Provided program using examples:
#include <stdio.h>
int main() {
int num;
printf("Enter an integer: ");
scanf("%d", &num);
if(num % 2 == 0)
printf("%d is even.", num);
else
printf("%d is odd.", num);
return 0; }
08. Write a C program for using If …. else and else if….
#include <stdio.h> int main () { int age; printf("Enter value of age: "); scanf("%d", &age); if (age<2);{ printf("Intant\n");} else if (age<10);{ printf("Child\n"); } else if (age<20);{ printf("Teenage\n"); } else if (age<30);{ printf("Adult\n"); } else { printf("%d\n"); } return 0; }
Thank You!
