Answer 1

Answer:

n=-4

m=4

Explanation:

try to do this by solving only first iteration

mark me as braintliest.

Answer 2

The output of the given code will be n= 6 and m= 5.

Explanation:

In the given code there is some error so, the correct code can be described as follows:

#include <iostream> //defining header file

using namespace std;

int main() //defining main method

{

int m, n = 0; //defining integer variable

for(m = 1;m <= 4;m++) //defining loop that counts m value

{

n += m; // add value in n variable

n--; //decrement the value of n by 1

}

cout<<"n: "<<n<<endl; //print value of n

cout<<"m: "<<m<<endl; //print value of m

return 0;

}

Description of the code:

• In the above program, two integer variable "n and m" is declared, in which variable "n" assigns a value that is equal to 0.
• In the next step, a for loop is declared, which uses variable "m", that starts from 1 and ends when its value is equal to 4.
• Inside the loop variable n adds m variable value and in the next line, variable n decreases its value by 1, and outside the loop, it will prints n, m variable value.
