what is wrong in this codes?

[nennahs24]

this is the codes:

#include<stdio.h>
#include<stdlib.h>
int main()
{
char option,pin,transaction;
int deposit, withdraw;
option='0';
 
 
 
printf("WELCOME TO SAMUEL'S BANK\n");
printf("------------------------------\n\n");
printf("Main Menu\n");
printf("------------------------------\n");
printf("1)Enter Pin #\n");
printf("2)Exit\n");
printf("------------------------------\n\n");
scanf("%c", &option);
 
 
 
 
 
 
{
system ("cls");
printf("Pin Number Verification\n");
printf("------------------------------\n\n");
printf("Please enter your pin number: ");
scanf("%s", &pin);
 
 
 
 
 
 
 
//if(inputfile ==NULL)
{
printf("Unable to open input file\n");
}
return 1;
 
 
system ("cls"); 
printf("Transactions\n");
printf("------------------------------\n");
printf("1)Deposit\n2)Withdraw\n3)Statement\n4)Exit \n");
printf("------------------------------\n");
scanf("%s",&transaction);
}
 
 
 
 
if (transaction =='1')
 
{
system ("cls");
printf("Deposit\n");
printf("------------------------------\n\n");
printf("Please enter the amount of money you would like to deposit: ");
scanf("%d", &deposit);
}
 
if (transaction =='2')
 
{
system ("cls");
printf("Withdraw\n");
printf("------------------------------\n\n");
printf("Please enter the amount of money you would like to withdraw: ");
scanf("%d", &withdraw);
}
 
if (transaction=='3')
 
{
system ("cls");
printf("Statement\n");
printf("------------------------------\n\n");
}
 
 
 
 
 
 
 
return 0;
 
 
}

when i will start to run it . the only mistake is this part:



//if(inputfile ==NULL)



that's the only mistake !!!

thanks !

It looks to me like most of those blank lines in your source listing should contain something, in many cases function headers I suspect and possibly some control structures.

Where did you copy it from?

[nennahs24]

i copy it here at bytes.com

[Banfa]

In that case i suggest that you start again and write the code with the functionality that you want it to have rather than copying a half baked piece of code some somewhere else that you don't understand.
