 Write a C program to calculate simple interest. The program

should accept the principal amount, rate of interest, and time period as input.

Solution:

C

#include <stdio.h>

int main() {
    float principal, rate, time, simple_interest;

    printf("Enter the principal amount: ");
    scanf("%f", &principal);

    printf("Enter the annual rate of interest (in percentage): ");
    scanf("%f", &rate);

    printf("Enter the time period (in years): ");
    scanf("%f", &time);

    simple_interest = (principal * rate * time) / 100;

    printf("\nSimple Interest = %.2f\n", simple_interest);

    return 0;
}

Question 3: Find the Largest of Three Numbers

Problem: Write a C program to find the largest of three different numbers entered by the user.

int main() {
    int num1, num2, num3;

    printf("Enter three numbers: ");
    scanf("%d %d %d", &num1, &num2, &num3);

    if (num1 >= num2 && num1 >= num3) {
        printf("The largest number is: %d\n", num1);
    } else if (num2 >= num1 && num2 >= num3) {
        printf("The largest number is: %d\n", num2);
    } else {
        printf("The largest number is: %d\n", num3);
    }

    return 0;
}

Question 4: Print Numbers from 1 to 10

Problem: Write a C program to print numbers from 1 to 10 using a loop.

Solution:

C

#include <stdio.h>

int main() {
    int i;

    for (i = 1; i <= 10; i++) {
        printf("%d\n", i);
    }

    return 0;
}

Question 5: Calculate Sum and Average

Problem: Write a C program to find the sum and average of two numbers entered by the user.

Solution:

C

#include <stdio.h>

int main() {
    int num1, num2, sum;
    float average;

    printf("Enter the first number: ");
    scanf("%d", &num1);

    printf("Enter the second number: ");
    scanf("%d", &num2);

    sum = num1 + num2;

    average = (float)sum / 2;

    printf("\nSum = %d\n", sum);
    printf("Average = %.2f\n", average);

    return 0;
}

Question 6: Area and Perimeter of a Rectangle

Problem: Write a C program to calculate the area and perimeter of a rectangle. The program should take the length and width as input.

Solution:

C

#include <stdio.h>

int main() {
    float length, width, area, perimeter;

    printf("Enter the length of the rectangle: ");
    scanf("%f", &length);

    printf("Enter the width of the rectangle: ");
    scanf("%f", &width);

    area = length * width;
    perimeter = 2 * (length + width);

    printf("\nArea of the rectangle = %.2f\n", area);
    printf("Perimeter of the rectangle = %.2f\n", perimeter);

    return 0;
}

Question 7: Celsius to Fahrenheit Conversion

Problem: Write a C program to convert temperature from Celsius to Fahrenheit.

Solution:

C

#include <stdio.h>

int main() {
    float celsius, fahrenheit;

    printf("Enter temperature in Celsius: ");
    scanf("%f", &celsius);

    fahrenheit = (celsius * 9 / 5) + 32;

    printf("\nTemperature in Fahrenheit = %.2f\n", fahrenheit);

    return 0;
}

Question 8: Factorial of a Number

Problem: Write a C program to find the factorial of a positive integer entered by the user.

Solution:

C

#include <stdio.h>

int main() {
    int n, i;
    unsigned long long factorial = 1; // Use long long for larger numbers

    printf("Enter a positive integer: ");
    scanf("%d", &n);

    if (n < 0) {
        printf("Factorial is not defined for negative numbers.\n");
    } else {
        for (i = 1; i <= n; ++i) {
            factorial *= i;
        }
        printf("Factorial of %d = %llu\n", n, factorial);
    }

    return 0;
}

Question 9: Check for a Leap Year

Problem: Write a C program to check if a year is a leap year or not.

Solution:

C

#include <stdio.h>

int main() {
    int year;

    printf("Enter a year: ");
    scanf("%d", &year);

    if ((year % 400 == 0) || (year % 4 == 0 && year % 100 != 0)) {
        printf("%d is a leap year.\n", year);
    } else {
        printf("%d is not a leap year.\n", year);
    }

    return 0;
}

Question 10: Sum of Digits

Problem: Write a C program to find of sum of digits of given number. 

Solution:

C

#include <stdio.h>

int main() {
    int n, sum = 0, remainder;

    printf("Enter an integer: ");
    scanf("%d", &n);

    // Loop continues until n becomes 0
    while (n != 0) {
        remainder = n % 10;
        sum += remainder;
        n /= 10;
    }

    printf("Sum of digits = %d\n", sum);
