Question

I am trying to change my code so i no longer need the function that reads in the users base and height input but rather uses the implementation of argument vector in C. I want to accept command line arguments and have it calculate my area.

so i want to type this into the command line and have it calculate my area

project1 5 4

#include <stdio.h>

void userDimensions(float *base, float *height) {
    scanf("%f", base);
    scanf("%f", height);
}

float calcArea(float base, float height) {
    float area;
    area = base * height;
    return area;
}

int main() {
    float base, height, area;
    userDimensions(&base, &height);
    area = calcArea(base, height);
    printf("The area is %f ", area);
    return 0;
}

CODE :

#include<stdio.h>

#include<conio.h>

float calcArea(float base, float height)
{
float area;
area = base * height;
return area;
}

int main(int argc,char *argv[])

{

float base,height;

float area;

base = atof(argv[1]);

height = atof(argv[2]);

area = calcArea(base, height);

printf("The area is %f ", area);

return 0;
}

OUTPUT :

./main 10 10

The area is 50
