  1. Control Statements in C

  2. C Keywords auto double int struct breakelse long switch case enum register typedef char extern return union const float short unsigned continuefor signed void defaultgoto sizeof volatile doif static while The words in bold print are used in control statements. They change the otherwise sequential execution of the assignment statements in a function block

  3. assignment statement aResult = 10; aResult = countB;aResult = (aValue + 100) / countD;aResult = sqrt (aValue);

  4. block of statements {constint MAX_BINS = 11;int orderNumber;int binNumber;printf("Enter order number: ");scanf("%d", &orderNumber);binNumber = orderNumber % MAX_BINS;printf("Bin number is %d\n", binNumber);}

  5. simple “if” statement if (aNumber != 1000) countA++;

  6. “if” with a block of statements if (aValue <= 10){ printf("Answer is %8.2f\n", aValue); countB++;}// End if

  7. “if” – “else” with a block of statements if (aValue <= 10){ printf("Answer is %8.2f\n", aValue); countB++;}// End ifelse{ printf("Error occurred\n"); countC++;}// End else

  8. nested “if” statement if (aValue == 1) countA++;elseif (aValue == 10) countB++;elseif (aValue == 100) countC++;else countD++;

  9. “while” with a single statement while (aResult >= 1000) aResult = aResult / aValue;

  10. “while” with a block of statements while (aResult >= 1000) { aResult = aResult / aValue; printf("Result is %9.4f\n", aResult); } // End while

  11. “while” with nested “if” statements aResult = MAX_VALUE; while (aResult >= 1000) { countW++;// nested if statementif (aValue == 1) countA++;elseif (aValue == 10) countB++;elseif (aValue == 100) countC++;else countD++; aResult = aResult / aValue; } // End while

  12. “while” performing an infinite loop while (1) { receiveFrom (aClient, aRequest); theResults = processRequest(aRequest); sendTo (aClient, theResults); } // End while

  13. “for” with a single statement for (i = 1; i <= MAX_LENGTH; i++) printf("#");

  14. “for” with a block of statements for (i = 0; i < MAX_SIZE; i++) { printf("Symbol is %c\n", aBuffer[i]); aResult = aResult / i; } // End for

  15. “for” performing an infinite loop for (;;) { receiveFrom (client, request); results = processRequest(request); sendTo (client, Results); } // End for

  16. “switch” statement switch (aNumber) {case 1 : countA++;break;case 10 : countB++;break;case 100 :case 500 : countC++;break;default : countD++; } // End switch 
