Question :

What is a memory leak? How can we avoid it?

Answer :

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; © CoolInterview.com Today's Special: Get Free Magazine from SAP now!
