lol
so you sent me a link to read how to ask for help? So what bit of there was I unpolite or whatever .... and yeh i did read it and yeh i got it fixed

IF i was asking for help from scratch with no code id understand you guys being off handish a simple ... hey look at line so and so ... thats all i needed

anywho ... best not to ask help from other IT guys ... and i cant really point fingers at u guys only even the people i study with are the same

Hey narue
could you please just tell me exactly what to do where
because i have this assignment due in 30 mins. If i had more time I would have worked it out

    fp=fopen("CityRain.txt","r+");

                npos++;

 	         monthvalues[1][monthnum-1]=rainfall;
        else
             monthvalues[npos-1][monthnum-1]=rainfall;
 	     count++;
   
     }
     printf("City              Jan      Feb    Mar    Apr    May    Jun\n\0");
      for(i=1;i<5;i++)  
      {               
             printf("%s\t\0",cityname[i]);
             if(i!=2)printf("\t\0");
            for(j=0;j<6;j++)
                  printf("%d\t\0",monthvalues[i][j]);
             printf("\n\0");
      }
     getch();
     return 0;
}

See i have added the'\0' still dosent change

also the output file is supposed to have just one city name and its stats horizontally next to it ... i don't know where I went wrong because its putting these other city names too

ermm ok ... where do i put that '\0' because the code is working right now i do not want to go and mess it up

Hi i got this progamm working fine
it is supposed to read a comma delimited text file store as an array and the output a formatted version
The problem is its outputting something really weird I dont know why.

The text file it is supposed to read

             printf("\n");
      }
     getch();
     return 0;

Am supposed to get a better looking output
But this is what I get
OUTPUT

Please tell me where I am wrong, because am …

hey its me again
i dont know whats the issue it just wont work
am using visual studio as the compiler

I will just post the entire code up
see what u guys think

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

void main()

{
	int emp_id;
	float hours;
	float mon, tue, wed, thur, fri;
	float norm_pay, over1_pay, over2_pay, over_pay;
	char dep_code;
	char choice;

	
	printf("Do you want to enter any more employee details (Y/N): ")
	scanf("%c%*c", &choice);

	do
	{

	printf("Enter employee Id: ");
	scanf("%d%*c", &emp_id);

	printf (" Please enter the hours worked for each day in the week when promted to \n");

	do
	{
		printf ("Please enter the hours worked on Monday: ");
		scanf ("%f.2%*c",&mon);
		if (mon > 12)
		{
			printf("\n Invalid hours were entered, the hours should not exceed 12 hours");
			printf("\n Please enter the hours worked on Monday:");
			scanf ("%f.2%*c",&mon);
		}
		else
			break;
	} while (mon !> 12);

	do
	{
		printf ("Please enter the hours worked on Tuesday: ");
		scanf ("%f.2%*c",&tue);
		if (tue > 12)
		{
			printf("\n Invalid hours were entered, the hours should not exceed 12 hours");
			printf("\n Please enter the hours worked on Tuesday:");
			scanf ("%f.2%*c",&tue);
		}
		else
			break;
	} while (tue !> 12);

	do
	{
		printf ("Please enter the hours worked on Wednesday: ");
		scanf ("%f.2%*c",&wed);
		if (wed > 12)
		{
			printf("\n Invalid hours were entered, the hours should not exceed 12 hours");
			printf("\n Please enter the hours worked on Wednesday:");
			scanf ("%f.2%*c",&wed);
		}
		else
			break;
	} while (wed !> 12);

	do
	{
		printf …

hey Kunal thanks for that - didnt think of a do ... while loop

but the requirement of the program is to ask if i want to add new employee after every entry - with the solution u just gave me - it just keeps asking for the employee code over and over again - dosent exit at any point

i cant understand what you r actually trying to do..
can you post your whole code here?

// This programe is going to be used to calculate the payroll of employees in a comapany//


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

void main()

{
	
	char choice, N, Y;
	int emp_id;
    
	printf ("Would you like to enter in any more employees: ");
	scanf ("%c%*c", &choice, &Y, &N);
    while ( choice != N && choice == Y)
	{ 
	

	printf ("please enter employee number: ");
	scanf ("%d%*c", &emp_id);
	
	}
	
	
	system("pause");










}

I have taken out the rest of the working within the while loop
just left the emp id bit for an example

done
I did do the scanf bit forgot to include it here
then I was including the Y and N as 'Y' and 'N'
changed that and the == bit - now it just dosent compile saying some kind of fatal error
lol

Hi
have done the whole program but now am stuck at what initially seemed like a simple thing a repitation loop
the program is supposed to ask the user if he/ she wants to continue with adding more data - if no exit and continue with the other stuff.

char choice, y, Y, n,  N;

while (choice != N && choice = Y)
{code 
code
code
)

now it keeps coming up with 3 different errors
1 it either just crashes
2 it just keeps doing the stuff of the while loop
3 it keeps telling me choice hasnt been initalized

I have just put in the bits thats causing a problem the rest of the program is fine
