Answer 1

Summary of my solution: In my solution, I will be defining the key differences and syntax with code snippets in C language. Solution: What is the difference between a “while” loop and a “for” loop? • In while loop, we have to initialize the iterator outside the definition of while loop but in for loop the iterator is defined within its syntax or definition. In while loop, inside its definition, we have to increment it explicitly (manually) but in for loop it's defined in the syntax or definition. In the syntax of while loop we just give condition checking but in for loop we initialize iterator, check loop condition and increment the iterator in its syntax. #include<stdio.h> int main() int arr[5] = {1, 2, 3, 4, 5}; /*Example of while loop / int i=0; //initializing a iterator while (i<5) // syntax of while and condition checking printf("%d", arr[i]); i++; //incrementing the iterator printf("\n"); /*Example of for loop* / for(int j=0; j<5; j++) // syntax of for loop; initialization, condition checking //incrementing all within the syntax printf("%d", arr[j]);

What is the difference between the break and the continue statement? • The key difference is break is used to break out of the loop even if loop is not finished and continue is used to keep loop running for even if a certain condition does not met. • Break statement is helpful when you don't know how many times the loop will run but you have to exit out of the loop when a certain condition is met. Continue statement is useful when you don't want to exit the loop even if a certain non- preferable condition come around and skips all other statements in loop that appear after the continue. #include<stdio.h> int main() 1{ /*Example of break statement / printf("Output of break statement: "); for (int i=1; i<10; i++) if(i%4==0) break; else printf("%d", i); /*Example of continue statement / printf("\nOutput of continue statement: "); for(int i=1; i<10; i++) if(i%4==0) continue; else printf("%d", i); "C:\Users\. . Desktop\for.exe" Output of break statement: 1 2 3 Output of continue statement: 1 2 3 5 6 79 Process returned 0 (0x0) execution time: 0.085 S Press any key to continue.
