In C++
Create an array of random 10 random numbers. Use the "range-based for loop" (sometimes called "enhanced for loop") to put the values into the array (users choice of number) and use the "range-based for loop" to output the numbers to the console.
In C++
Create an array of 100 random numbers between 1 and 1000. Ask the user for a number. Search the array and check if the users number is in the array.
#include <stdio.h>
int main(){ int arr[10]; int i; for (i=0; i<10; i++){ arr[i] = i; } for (i=0; i<10; i++){ printf("arr[%d] = %d\n", i, arr[i]); } return 0;}
Copy the code and modify it as follows:
Add another separate array of 10 integers. The following code parts are to be added (in the same order as specified) after the printing of the values of the first array:(1) Copy the content of the first array to the second array. Add 10 to each of the values of the second array. Make use of a single loop to achieve this part.(2) Print each element of the second array. Make use of another loop for this part

- in java Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. Output all elements of userCounts in reverse order, following each element with a space, including the last. After the final output, end with a newline. Ex: If the input is 4 54 56 75 7 then the output is: Array contents in reverse: 7 75 56 54 Note: The loop should start with i = userCounts.length - 1 and end with i = 0. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class UserLog { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; inti; numVals=scnr.nextInt(); int[] userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); } System.out.print("Array contents in reverse: "); /* Your code goes here */ } }arrow_forwardWhat is the value of d['a'] after the following lines of code are executed? d = {} d['a'] = 1 2 = [,q.]p d['c'] = 3 d['a'] = 4arrow_forwardThis is needed in JAVAarrow_forward
