Write the definition of a function named isPositive, that receives an integer argument and returns true if the argument is positive, and false otherwise. So, if the argument's value is 7 or 803 or 141 the function returns true. But if the argument's value is -22 or -57, or 0, the function returns false.
Answer:
// header files
#include <iostream>
using namespace std;
// required function
bool isPositive(int num)
{
// check if number is positive
if (num > 0)
{
// return true
return true;
}
// if number is 0 or negative
else
{
// retrun false
return false ;
}
}
// main function
int main() {
// test the function with different values
cout<<isPositive(7)<<endl;
cout<<isPositive(803)<<endl;
cout<<isPositive(141)<<endl;
cout<<isPositive(-22)<<endl;
cout<<isPositive(-57)<<endl;
cout<<isPositive(0)<<endl;

You have to write a program that will read a number followed by a series of bit operations from a file and perform the given operations sequentially on the number.
The operations are as follows:
set(x, n, v) sets the nth bit of the number x to v
comp(x, n) sets the value of the nth bit of x to its complement (1 if 0 and 0 otherwise)
get(x, n) returns the value of the nth bit of the number x
The least significant bit (LSB) is considered to be index 0.
Input format: Your program will take the file name as input. The first line in the file provides the value of the number x to be manipulated. This number should be considered an unsigned short. The following lines will contain the operations to manipulate the number. To simplify parsing, the format of the operations will always be the command name followed by 2 numbers, separated by tabs. For the set(x, n, v) command, the value of the second input number (v) will always be either 0 or 1. For the comp(x, n) and get(x, n) commands the value of the second input number will always be 0 and can be ignored. Note that the changes to x are cumulative, rather than each instruction operating independently on the original x.
Output format: Your output for comp and set commands will be the resulting value of the number x after each operation, each on a new line. For get commands, the output should be the requested bit’s value.
Example Execution:
For example, a sample input file "file1.txt" contains the following (except the annotation comments):
5 ---------------------------------# x = 5
get 0 0 -------------------------# get(x, 0), ignoring second value (0)
comp 0 0 ----------------------# comp(x, 0), ignoring second value (0)
set 1 1 --------------------------# set(x, 1, 1)
The result of the sample run is:
$ ./first file1.txt
