Nested loops

Nested Loops

• A loop can be nested inside of another loop.
• C++ allows at least 256 levels of nesting
• When working with nested loops, the outer loop changes only after the inner loop is completely finished

The syntax for a nested while

loop statement in C++

while(condition) { while(condition) { statement(s); } statement(s); // you can put more statements. }

The syntax for a nested

do...while loop statement in C++

do { statement(s); // you can put more statements. do { statement(s); } while( condition ); } while( condition );

7 *Nested loops (loop in loop) cin >> a >> b; for (int i = 0; i < a; i++) { for (int j=0; j<b; j++) { cout << “”; } cout << endl; }

8 *Nested loops (2) int a,b; cin >> a >> b; for (int i = 0; i < a; i++) { for (int j=0; j<b; j++) { if (j > i) break; cout << “”; } cout << endl; }
