Question

All program should be in C

Write its pseudocode and draw its flowchart) to prompt the user to input the variables to solve the following problem:

X2 + X×Y/Z - W*V3

Note 1: You should ask the user to input 5 numbers to be able to do this calculation.

Note 2: You can use multiplication instead of power if you do not want to use it (as we have not officially covered it).

Write a program (compile and run), pseudocode, and draw a flowchart for each of the following problems:

a) Obtain three numbers from the keyboard, compute their product, and display the result.

Ans:

b) Obtain two numbers from the keyboard, and determine and display which (if either) is the smaller of the two numbers.

Ans:

c) Obtain a series of positive numbers from the keyboard, and determine and display their average (with 4 decimal points). Assume that the user types the sentinel value -1 to indicate "end of data entry."

Ans:

Answer 1

running code.

#include <stdio.h>

int main()
{
    
    // first
    double x, y, z, w, v;
    printf("Enter x, y, z, w, v.\n");
    scanf("%lf%lf%lf%lf%lf", &x, &y, &z, &w, &v);
    double x2 = x * x;
    double v3 = v * v * v;
    printf("Answer: %lf\n\n", x2 + x*(y/z) - w*v3);
    
    // second
    printf("Enter x, y, z.\n");
    scanf("%lf%lf%lf", &x, &y, &z);
    double ans = x * y * z;
    printf("Answer: %lf\n\n", ans);
    
    // third
    printf("Enter x, y.\n");
    scanf("%lf%lf", &x, &y);
    double min;
    if(x < y) {
        min = x;
    } else {
        min = y;
    }
    printf("Minimum: %lf\n\n", min);
    
    // fourth
    printf("Enter series of numbers, -1 to end\n");
    double s = 0.0;
    int c = 0;
    do {
        scanf("%lf", &x);
        if(x != -1) {
            s += x;
            c++;
        }
    } while(x != -1);
    printf("Avearage: %lf\n", s/c);
    
    return 0;
}
