Jump Statement makes the control jump to another section of the program unconditionally when encountered. It is usually used to terminate the loop or switch-case instantly. It is also used to escape the execution of a section of the program. There are 4 jump statements: Break Continue Goto Return 1. Break Jump Statement A break statement is used to terminate the execution of the rest of the block where it is present and takes the control out of the block to the next statement. It is mostly used in loops and switch-case to bypass the rest of the statement and take the control to the end of the loop. Example: #include int main() { int i; for (i = 1; i <= 10; i++) { printf('%dn', i); if (i == 5) break; } return 0; } The output of above program is 1 2 3 4 5 2. Continue Jump Statement The continue jump statement like any other jump statement interrupts or changes the flow of control during the execution of a program. Continue is mostly used in loops. Rather than terminating the loop it stops the execution of the statements underneath and takes control to the next iteration. Example: #include int main() { int i, j; for (i = 1; i < 5; i++) { if (i == 2) continue; printf('%dn', i); } return 0; } The output of above program is 1 3 4 3. Goto Jump Statement goto jump statement is used to transfer the flow of control to any part of the program desired. The programmer needs to specify a label or identifier with the goto statement. Example: #include int main() { int i, j; for (i = 1; i < 5; i++) { if (i == 2) goto jmpSection; printf('%dn', i); } jmpSection: printf('Two'); return 0; } The output of above program is 1 Two 4. Return Jump Statement Return jump statement is usually used at the end of a function to end or terminate it with or without a value. It takes the control from the calling function back to the main function(main function itself can also have a return). #include char func(int ascii) { return ((char) ascii); } int main() { int ascii; char ch; printf('Enter any ascii value in decimal: n'); scanf('%d', & ascii); ch = func(ascii); printf('The character is : %c', ch); return 0; } In this program, we have two functions that have a return type but only one function is returning a value[func()] and the other is just used to terminate the function[main()]. Program to check whether a number entered is prime or not #include int main() { int n, i, flag = 0; printf('Enter a positive integer: '); scanf('%d', &n); for (i = 2; i <= n / 2; ++i) { if (n % i == 0) { flag = 1; break; } } if (n == 1) { printf('1 is neither prime nor composite.'); } else { if (flag == 0) printf('%d is a prime number.', n); else printf('%d is not a prime number.', n); } return 0; } The output of above program is Enter a positive integer: 29 29 is a prime number. Enter a positive integer: 6 6 is not a prime number.
