Question

I have a problem with the following code

#include <stdio.h>
int main()                /* Tidsberäkning YO */
{
    float tid1, tid2;
    printf("Tid i första åket? ");
    scanf("%f", %tid1);
    printf("Tid i andra åket? ");
    scanf(%f", &tid2);
    printf("Total Tid: %f\n", tid1+tid2);
    printf(Genomsnittlig tid: %f\n", (tid1+tid2)/2);
}

And here is the error log

Answer 1

scanf(%f", &tid2);

and

printf(Genomsnittlig tid: %f\n", (tid1+tid2)/2);

are missing the first quotation mark. Change to:

printf("Genomsnittlig tid: %f\n", (tid1+tid2)/2);

and

scanf("%f", &tid2);
