PPS Unit 2 Important Programs

Unit 2 - Fundamentals of C

2.1 - Write a C Program to convert temperature from Fahrenheit to Celsius and vice versa. [S-10, W-16, S-18, W-19]

#include <stdio.h>

int main()

{

    float fh,cl;

    int choice;

    printf("\n1: Convert temperature from Fahrenheit to Celsius."); 

    printf("\n2: Convert temperature from Celsius to Fahrenheit.");

    printf("\nEnter your choice (1, 2): ");

    scanf("%d",&choice);

    if(choice ==1)

    {

        printf("\nEnter temperature in Fahrenheit: ");

        scanf("%f",&fh);

        cl= (fh - 32) / 1.8;

        printf("Temperature in Celsius: %.2f",cl);

    }

    else if(choice==2)

    {

        printf("\nEnter temperature in Celsius: ");

        scanf("%f",&cl);

        fh= (cl*1.8)+32;

        printf("Temperature in Fahrenheit: %.2f",fh);

    }

    else

    {

        printf("\nInvalid Choice !!!");

     }

     return 0;

}

2.2 - Develop an application program to convert and print distance between two cities in meters, feet, inches & centimeters. The distance between the two cities (In KM) is input through keyboard. [W-17]

#include<stdio.h>

int main()

{

float km, m, cm, feet, inch;

printf("Enter distance in kilometers: ");

scanf("%f",&km);

m = 1000 * km;

cm = 1000 * 100 * km;

feet = 3280.84 * km;

inch = 39370.08 * km;

printf("The distance in Feet: %f\n", feet);

printf("The distance in Inches: %f\n", inch);

printf("The distance in Meters: %f\n", m);

printf("The distance in Centimeters: %f\n", cm);

return 0;

}

2.3 - Write a program that reads two numbers from the keyboard and gives their addition, subtraction, multiplication, division and modulo. [W-17]

#include<stdio.h>

int main()

{

int a,b;

printf("Enter First Number : ");

scanf("%d",&a);

printf("\nEnter Second Number : ");

scanf("%d",&b);

printf("\nAddition of %d & %d is : %d", a, b, a+b);

printf( "\nSubtraction of %d & %d is : %d", a, b, a-b);

printf("\nMultiplication of %d & %d is : %d", a, b, a*b);

printf("\nDivision of %d & %d is : %d", a, b, a/b);

printf("\nModulo of %d & %d is : %d", a, b, a%b);

return 0;

}

2.4 - Write a program to find out an area of a circle. [S-17]

#include<stdio.h> int main() { float r,area; printf("Enter the radius : "); scanf("%f",&r); area = 3.14*r*r; printf("Area of a circle : %.2f",area); return 0; }

2.5 - Write a program to find area of triangle. [S-20]

#include <stdio.h>

int main()

{

    float base, hight, area;

    printf("Enter base of the triangle : ");

    scanf("%f", &base);

    printf("Enter hight of the triangle : ");

    scanf("%f", &hight);

    area=(base*hight)/2;

    printf("Area of the triangle = %.2f", area);

    return 0;

}

2.6 - Write code to find out largest of 2 numbers using ternary operator. [S-17]

#include <stdio.h>

int main()

{

    int a, b, num;

    printf("Enter 2 numbers : \n");

    scanf("%d %d", &a, &b);

    (a > b) ? (num = a) : (num = b);

    printf("Largest of %d and %d is %d\n", a, b, num);

    return 0;
