Chapter 5 loops structure

In the following for loop construct ( for(x=0; x>10; x++) ) which statement is executed only once ?

• (x=0; x>10;) only

• X++

• x=0

• X>10

Which loop is guaranteed to execute at least one time?

• For loop

• While loop

• Do while loop

• All of these

The output of the following code will be:

main()

{

for (int i=0; i<2; i++)

{

for (int j=0; j<4; j++)

{

printf("%d, %d\n",i ,j);

}

}

}

• Middle of the loop

• End of the loop

In do while loop , the test expression is written:
