Nested Loop Break How can we break a loop directly from another nested loop? e.g: for(int i=0;;i++){ for(int j=0;;j++){ if(matrix[i][j]==100){ goto break_pt; //exit both loops } else if(j==10){ break; } } } break_pt: 8th Jul 2017, 3:45 PM Karl T. + 5 Yo...

The combination of for loop and if statement is very common in array programming. The for loop iterates over the elements in the array, the if statement filters out the required elements and are processed. A shorthand for this combination is developed from the observation that the information ...
