There are 46 questions to complete.1) Choose a right C Statement.A) Loops or Repetition block executes a group of statements repeatedly.B) Loop is usually executed as long as a condition is met.C) Loops usually take advantage of Loop Counter2) Loops in C Language are implemented using.?A) While Block3) Which loop is faster in C Language, for, while or Do While.?A) forD) All work at same speed4) Choose correct C while loop syntax.A) while(condition) statementsB) statementswhile(condition)C) while(condition); statementsD) while() if(condition) statements 5) Choose a correct C for loop syntax.A) for(initalization; condition; incrementoperation) statementsB) for(declaration; condition; incrementoperation) statementsC) for(declaration; incrementoperation; condition) statementsD) for(initalization; condition; incrementoperation;) statementsExplanation: increment or decrement operation at third place.6) Choose a correct C do while syntax.A) dowhile(condition) statementsB) do while(condition) statementsC) do statementswhile(condition)D) do statementswhile(condition);Explanation: Semicolon after while(condition) is a must.7) What is the output of C Program.?int main() while(true) printf(RABBIT); break; return 0;A) RABBITB) RABBIT is printed unlimited number of times.Explanation: while(TRUE) or while(true) does not work. true is not a keyword.8) What is the output of C Program.?int main() int a=5; while(a==5) printf(RABBIT); break; return 0;A) RABBIT is printed unlimited number of timesExplanation: If there is no BREAK statement, while loop runs continuously util the computer hangs. BREAK causes the loop to break once and the statement below the while if any will be executed.9) What is the output of C Program.?int main() int a=5; while(a=123) printf(RABBIT); break; printf(GREEN); return 0;A) GREENC) RABBIT is printed unlimited number of times.Explanation: while(a=123) = while(123) = while(Non Zero Number). So while is executed. BREAK breaks the loop immediately. Without break statement, while loop runs infinite number of times.10) What is the output of C Program.?int main() int a=5; while(a >= 3); printf(RABBIT); break; printf(GREEN); return 0;A) GREENC) RABBIT is printed infinite timesExplanation: Notice a semicon(;) after while condition. It makes the printf and break statement blocks isolate.while(a >= 3) ;infinite loop printf(RABBIT); break;11) What is the output of C Program.?int main() int a=25; while(a <= 27) printf(%d , a); a++; return 0;A) 25 25 25Explanation: a++ is equivalent to a=a+1;a is incremented each time.12) What is the output of C Program.?int main() int a=32; do printf(%d , a); a++; while(a <= 30); return 0;A) 32Explanation: do block is executed even before checking while(condition) at least once. This prints 32. To loop for the second time, while (32 <= 30) fails. So, loop is quit.13) What is the output of C Program.?int main() int a=32; do printf(%d , a); a++; if(a > 35) break; while(1); return 0;A) No OutputExplanation: while(1) is infinite loop. So we kept if(condition) to break the loop. a++ is equivalent to a=a+1;14) Choose a correct C Statement.A) a++ is (a=a+1) POST INCREMENT OperatorB) a-- is (a=a-1) POST DECREMENT Opeartor--a is (a=a-1) PRE DECREMENT OpeatorC) ++a is (a=a+1) PRE INCRMENT Operator15) Choose correct Syntax for C Arithmetic Compound Assignment Operators.A) a+=b is (a= a+ b)a-=b is (a= a-b)B) a*=b is (a=a*b)a=b is (a = ab)16) What is the output of C Program.?int main() int k, j; for(k=1, j=10; k <= 5; k++) printf(%d , (k+j)); return 0;A) compiler errorExplanation: You can initialize any number of variables inside for loop.17) What is the output of C Program.?int main() int k; for(k=1; k <= 5; k++); printf(%d , k); return 0;A) 1 2 3 4 5Explanation: Semicolon at the end of for(); isolates the below print() block. After for loop is over, k value is 6.for(k=1; k <= 5; k++) ; printf(%d , k);18) What is the output of C Program.?int main() int k; for(;;) printf(TESTING); break; return 0;A) No OutputExplanation: for(;;) loop need not contain any initialization, condition and incredecrement sections. All are optional. BREAK breaks the FOR Loop.19) What is the output of C Program.?int main() int k; for(printf(FLOWER ); printf(YELLOW ); printf(FRUITS )) break; return 0;A) Compiler errorExplanation: for(anything; anything; anything) is Ok. printf(YELLOW) prints YELLOW and returns 1 as result. So for loop runs forever. Actually break is saving us from quitting the for loop. Only after checking condition and executing the loop statements, third section is executed. break causes the loop to quit without incredecrement section.20) What is the way to suddenly come out of or Quit any Loop in C Language.?A) continue; statementExplanation: eg.while(condition)break;
