Did alot of searching but to be honest I have no idea...

Hey C programming forums
its me again :P
Still doing basics of C

I get alot of whats being told in the book, and its helping me think for myself and after about a good 20 mins of searching I have no idea how to fix this error.

As an exercise I have to build a program that scans values of wages, hours worked, and tax rate which than becomes a final value in the variable final_payment.

Unfortunately I keep getting segmentation errors when everyone enters their hour wages (first variable).
Now I get 2 warning messages when compiled so maybe that is the reason why and I can honestly tell you I don't completely get exactly about conversion specifiers and how different types integrate with each other so I am hoping you guys/girls can clear things up.

Code:

#include <stdio.h>

int main(void)
{
    float u_wage;
    int tax_rate;
    int u_hours;
    float final_payment;

    printf("Enter the amount of pay you get per hour: ");
    scanf("%f", u_wage);
    printf("Enter the amount of hours you worked: ");
    scanf("%d", u_hours);
    printf("Enter your current tax rate to be deducted from your pay: \n");
    final_payment = (u_wage * u_hours) - (tax_rate/100);
    printf("Your final payment is %f", final_payment);

    return 0;

}

Warnings:

Code:

|warning: format ‘%f’ expects type ‘float *’, but argument 2 has type ‘double’|
warning: format ‘%d’ expects type ‘int *’, but argument 2 has type ‘int’|
||=== Build finished: 0 errors, 2 warnings ===|

scanf does not expect variables themselves, it expects the address of the variable.

To supply the address of a variable, you use an ampersand (&) before the variable name.

scanf("%s", &string );

I'm assuming you haven't covered pointers yet, it will become more clear when you do. For now just remember to supply the address of a variable when a function expects it.

wow i fail lol
im such a dumbass :P
this was like chapter 1 stuff and totally slipped my mind that for scanf i gotta supply that symbol ahah jeez.

noob error XD

Thanks for the help
