1. use scanf and printf to get an input as integer and output this integer using %d format: int a; printf ("Input an integer: "); scanf("%d", &a); printf ("Your integer is %d\n", a); 2. integer arithmetic: int a, b, c; a = 100; b = a - 20; c = a* b + 50; printf("a = %d b = %d c = %d\n", a, b, c);

a=2 b=3 c=((a**2)+(b**3))//(a*b) print(c) What is the output of the above program

The output of the code is: int main() { int x = 10; { int x = 0; printf("%d",x); } return 0; }

A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("After 6 hours: %.2f mg\n", yourValue); Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg. 1 import java.util.Scanner; 3 public class LabProgram { 06∞VOSAWNA 2 4 5 7 8 9 10 } PER 11 } 12 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); double caffeineMg; // "double" supports floating-point Like 75.5, versus int for integers Like 75.
