    Stoping my array

    I have the following:

    char super[30];
    for(nt = 0; nt < 30; nt++)
    cin >> super[nt];

    I am inputting a line such as 24 + 5 - 2 =
    and I want the array to stop letting characters in once someone types the = sign and hits enter. Any ideas? thanks for your help in advance!

    I have the following:

    char super[30];
    for(nt = 0; nt < 30; nt++)
    cin >> super[nt];
    Well this is not the right way to do this.
    A better way would be to use:
    Code:
    while(nt!="=")
    {
       //do code here
    }

    This will work, but does require the user to hit enter. It reads to = sign and stopes. The cin.ignore is to clear everything from the = to the enter.
    Code:
    #include <string>
    #include <iostream>
    using namespace std;
    
    int main(int argc, char* argv[])
    {
    	char  cLine[81];
    	cin.get( cLine, 80, '=' );
    	cin.ignore( 80, '\n' );
    
    	return 0;
    }
