Question

I already have a C Program that is complete and correct, but I just want it to have an error checking element. For instance, if someone adds too many characters to an array with the specified length, I want the user to be able to receive an error message and re-type an accurate amount of characters. Example: If someone typed in 30001 characters in the string for a 30000 character limit, a message should be printed and the user should be able to re-type a correct value.

Here is a link with the program details (all of it complete, but I'll put it for your understanding):

https://www.dropbox.com/s/vv91smjitydrvbg/program_details.docx

Here is the completed code:

#include <stdio.h>

#include <string.h>

void func (char a[]);

int main (void)

{

int n;

char a[30000];

printf("How many strings would you like to zip? ");

scanf("%d",&n);

printf("Enter your string: ");

while(n--)

{

scanf("%s",&a);

func(a);

}

return 0;

}

void func(char a[])

{

int i,length= strlen(a),count=0;

char b=a[0];

for (i=0;i<length;i++)

{

if(a[i]==b)

{

count++;

}

else

{

printf("%d%c",count,a[i-1]);

count=1;

b=a[i];

}

printf("%d%c ",count,a[length-1]);

}
