    A memory leak can be avoided by making sure that whatever memory has been dynamically allocated will be cleared after the use of the same. for example

    int main()

    { char *myCharData[20];

    for (int nLoop =0;nLoop < 20; ++nLoop) { myCharData[nLoop ] = new char[256];

    strcpy(myCharData[nLoop],"SABITH");

    .......

    }

    .........................

    /*Some manipulations here using myCharData*/

    /*Now here we have to clear the data. The place can vary according to ur program. This being a simple program,u can clear at the end*/

    for(int nLoop =0;nLoop < 20; ++nLoop)
    {

    delete[] myCharData[nLoop ];

    }

    return 0;
