So here is the code, it ignores the while and I don't know why, it is supposed to start with the while as soon as you enter a value for the first printf
#include <stdio.h>
int main()
{
str WhoOwes,Fabri,Alen,Amilcar,Maxi,Lolo;
int RandomInt=0,Deudores;
printf("How many people owes?:");
scanf("&d",&Deudores);
while(RandomInt <= Deudores);
{
printf("who owes?:");
scanf("&c",&WhoOwes);
if(scanf("%c",&WhoOwes)==Fabri)
{
Fabri= Fabri+1;
printf("Fabri debe $",Fabri*4);
}
}
return 0;
}
Thanks!H

Change:
while(RandomInt <= Deudores);
To (remove the semicolon):
while(RandomInt <= Deudores)
Also, the delimiter you use in scanf should be %d not &d.
Further more, what type is str?
You are using scanf delimiter%d which is for an int to store into a str type which, I assume is some sort of a struct. If it is, this is not the way to do that. You have to store information into each part of the struct separately. Or change the type str to an int. This could be the reason why your while loop doesn't happen because you are trying to compare an int to a str:
while(RandomInt <= Deudores); // Deudores is a str
Then you are reading information twice by calling scanf() twice but you are only comparing what you get the second time. Also, the first time you read it you use the &c delimiter which is invalid. It should be %c. Further more, you create the str Fabri variable above with an invalid type str and also you don't give it a value anywhere in your code so you cannot do the comparison in the if statement:
scanf("&c",&WhoOwes);
if(scanf("%c",&WhoOwes)==Fabri)
Since you are using the character delimiter %c, you should declare WhoOwes and Fabri as char types to have consistent logic although it isn't technically required since int and char store interchangeable information. You must also initialize the Fabri variable to some char value.
However, in the end of your code you have the statement:
printf("Fabri debe $",Fabri*4);
This will not work because you are missing a delimiter where to print the Fabri*4 value.
Change that line to:
printf("Fabri debe %d$",Fabri*4); // add the %d delimiter to print the actual value
Since you are using Fabri in a calculation, you should then probably declare all your variables as int and read them using the %d delimiter, not %c.
Your program should look something like this:
#include <stdio.h>
int main()
{
int WhoOwes, Fabri, Alen, Amilcar, Maxi, Lolo; // these are int types not str types
int RandomInt = 0, Deudores;
Fabri = 5; // initialize Fabri to some value that can be used for comparisons
printf("How many people owes?:");
scanf("%d",&Deudores);
while(RandomInt <= Deudores);
{
printf("who owes?:");
scanf("%d",&WhoOwes); // use
if(WhoOwes == Fabri) // use what you scanned the first time to compare to Fabri
{
Fabri= Fabri+1;
printf("Fabri debe %d$",Fabri*4); // add the int delimiter %d to actually print the money amount
}
}
return 0;
}
