Assigning an expression to variables in C language

I have an assignment in C where i have to create a small program that would calculate some things. The only thing im struggling with is that according to said assignment, i need to let user declare x as 1.825*10^2 using scanf function. However, when doing that my program just exits.

Here’s the relevant part of my code

#include <stdio.h>
#include <math.h>

// VARIANT 2

int main()
{   
  
    float x, y, z, ans1, ans2, answer;
    printf("Declare x:\n");
    scanf("%f", &x);
    printf("Declare y:\n");
    scanf("%f", &y);
    printf("Declare z:\n");
    scanf("%f", &z);

    printf("%f %f %f \n", x,y,z);
}

Im declaring X in terminal as 1.825*pow(10,2). My guess is that scanf doesnt allow/read expressions – but the assignment is clear that i need to declare X via scanf.

>Solution :

First, what you’re describing is not "declaring" x. You’re describing reading in a value for x.

The %f format specifier for scanf expects a decimal floating point constant to be read, and the string 1.825*pow(10,2) is not such a constant.

The way you would specify such a value would be 1.825e2.
