expected function body after function declarator codeblocks

Question

I am trying to code a little program which calculates the price with fees.

There is two error messages :

7 : "Expected function body after function declarator"

9 : Expected identifier or "("

The code is :

#include <stdio.h>
#include <stdlib.h>


int main()

    var float : prix_ht,prix_ttc;

{

    //La taxe vaut 2,6 euros

    //Saisie du prix hors taxes
    printf("Saisir le prix hors taxes");
    scanf("%f",&prix_ht);

    prix_ttc==(prix_ht)+(2.6);

    printf("Le prix ttc est :%f",&prix_ttc);

    return 0;
}

If the purpose of the image is to provide extra information, then it is not serving it. It's unreadable. — Eugene Sh., Feb 23 '18 at 19:56

`var float : prix_ht,prix_ttc;` --> This doesn't look like a C language way of the variable declaration. — H.S., Feb 23 '18 at 20:04

var float : prix_ht,prix_ttc;

is not C code, you declare variables like this:

float prix_ht, prix_ttc;

And you should write this line inside your main function:

#include <stdio.h>
#include <stdlib.h>


int main()
{
    float prix_ht, prix_ttc;

    //La taxe vaut 2,6 euros

    //Saisie du prix hors taxes
    printf("Saisir le prix hors taxes");
    scanf("%f",&prix_ht);

    prix_ttc==(prix_ht)+(2.6);

    printf("Le prix ttc est :%f", prix_ttc);

    return 0;
}

Also note that I fixed your last printf line, you were passing a pointer to float.

And you should check the return value of scanf, you don't know if it was able to read a float and convert it. You should do

if(scanf("%f", &prix_ht) != 1)
{
    fprintf(stderr, "Could not read float for prix_ht\n");
    return 1;
}

And double == is for comparing

    prix_ttc==(prix_ht)+(2.6);

compares the value prix_ttc with prix_ht+2.6, it is not assigning it. You should use only one =:

    prix_ttc=(prix_ht)+(2.6);

@WeatherVane good catch, I missed the `==` instead of `=` on my first look at the code. — Pablo, Feb 23 '18 at 20:00

just put { after int main() and remove { on line no. 5
