Question

C language

Create the following programs:

Program to solve for Area of Rectangle

Variable inputs for length and width of integer data type

Variable output for area of integer data type

Program to find Area of Circle

variable array with 10 inputs from 3-30 by steps of 3

variable array with 10 solutions for Area of Circle of float data type

Program to solve for any angle with inputs of x and y using the standard Cartesian coordinate system

Use math.h library

Solve for output angle of float data type

Use hard coded input variables, and then use printf to output the solutions.

Answer 1

#include <stdio.h>

int main() {
    int length, width;
    printf("Enter length of rectangle: ");
    scanf("%d", &length);
    printf("Enter width of rectangle: ");
    scanf("%d", &width);
    printf("Area is %d\n", length*width);
    return 0;
}

#include <stdio.h>

#define PI 3.14159

int main() {
    int radius[10] = {3, 6, 9, 12, 15, 18, 21, 24, 27, 30}, i;
    double areas[10];
    for (i = 0; i < 10; ++i) {
        areas[i] = PI * radius[i] * radius[i];
    }
    // print result
    for (i = 0; i < 10; ++i) {
        printf("Area of circle with radius %d is %lf\n", radius[i], areas[i]);
    }
    return 0;
}
