Question

I'm trying to write a program in C that calculates the area of a rectangle. I need to have a function that gets dimensions from a user and stores them with pointers and addresses and another function that calculates the area... my question is how do i access that values from the dimension function so that I can use it in my calculation and main function.. for example.

void userDimensions(float *base, float *height){

scanf("%lf" , base);

scanf("%lf", height);

}

float calcArea(){

float area;

area = base * height;

return area;

}

int main{

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

}

i have never programmed in C and i'm having a hard time. Can anyone help me please?

#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;
}
