Question

What is wrong with the following for statement? 

for(i=0; j=0, i<10; ++i, j += i) {  
    k += i*i + j*j;   
}
  • A. It should include more than one statement in the statement block.
  • B. There should be a comma between i=0 and j=0.
  • C. It uses more than one loop index.
  • D. There should be a semicolon between j=0 and i<10. 


B and D.

Note

Commas are used to separate statements within the initialization and iteration parts of a for statement.

Semicolons are used to separate the initialization, loop condition, and iteration parts of the for statement.
