Question

we do mot expect you tomoany the approach or incorporate any additional library methods The function printPattern(int num) prints even or odd numbers based on the value of the input argument num (num 2 0) If the input number num is even, the function is expected to print the first num even whole numbers and in case it is odd, is expected to print the first num odd numbers. For example: given input 2, the function prints the string "O 2" (without quotes). The function compiles successfully but fails to print the desired result due to logical errors.

Answer 1

Solution for the given question are as follows -

Code :

#include <iostream>
using namespace std;
// printPattern - printPattern function defination
void printPattern(int num) {
// check num is even or odd
if (num % 2 == 0) {
// loop over num numbers and check each no is even or not and print i
for (int i = 0; i <= num; i++) {
if (i % 2 == 0) {
cout<< i << " ";
}
}
} else {
// loop over num numbers and check each no is odd or not and print i
for (int i = 0; i <= num; i++) {
if (i % 2 != 0) {
cout<< i << " ";
}
}
}
}
int main()
{
// local variable declaration
int n;
// get input from user
cout<<"Enter any number: ";
cin>> n;
// check for negative number
if (n < 0) {
cout<< "Invalid number";
}
// call to printPattern() function
printPattern(n);
return 0;
}

Code Screen Shot :

1 tinclude<iostream> 2 using names pace std; 3 // printPattern 4- void printPattern (int num) { printPattern function defination /check num is even or odd 5 if (num % 2 =- 0) { // Loop over num numbers and check each no is even or not and print i for (int i if (i % 2 6- 7 0; i <= num; i++) { 9 cout< i << " "; 10 } } } else { / Loop over num numbers and check each no is odd or not and print i for (int i = 0; i <= num; i++) { if (i % 2 ! = 0) { 11 12 13 14 15 16 cout< i << " "; 17 } } } 18 19 20 21 } int main) 23-{ 22 //Local vari able declaration int n // get input from user cout<<"Enter any number: cin>> n // check for negative number if (n< ) { 24 25 26 27 28 29 30- cout<< "Invalid number"; } /call to printPattern () function print Pattern(n); return 0; 31 32 33 34 35 36

Output :

Enter any number: 2 0 2 . .Program finished with exit code 0 Press ENTER to exit console.

Enter any number: 7 1 3 5 7 . .Program finished with exit code 0 Press ENTER to exit console.
