Thread: deleting specific numbers

For my final project in my C++ class we have to design a program that creates two arrays of 100 integers , and allows the user to append them,search,sort,insert,print,sum,mutiply and do all kinds of stuff with the arrays. it also asks us to ask the user if they want to delete specific integers from the array....i know how to design the loop and all, but my problem is this:
do you have the compiler replace the integer to be deleted with a null character, or how would you do it?
any and all help is appreciated, thank you!

OK so thats what i did,
in effect i wrote a function to delete the specific integer like such:

say i had a list of 5 numbers: 3 1 7 8 2. the user wants to delete the number 2.

void scratch(const int a[],int size,int target)
{
int index=0;
bool found=false;
while ((!found)&&(index<size))
if (target==a[index])
found=true;
else
index++;

if (found)
a[index]='\0' <-------line giving me problems
else
cout<<"Number specified is not on the list"<<endl;
}


The compiler just spits more and more garbage about this. what do you think could be wrong?
thank you!

instead of '\0' how about using -1 or -999 or some other number not expected in the arrray? I would be careful about putting a char into an int array as the compiler may well convert the char to it's ASCII equivalent and thereby place an unexpected but acceptable int into the array. Deletion with shifting of contents or changing int array into char array and restricting element values that way are alternatives. If negative values are allowed in the int array then I think deletion and shifting is probably the best solution.
