write out the code for this task

Answer 1

May be you missed something in your question so we'd analyzed all cases:

void operation1(int * ipt) //2+ipt
{
int a=2;
a+=ipt; //types do not match. a-int ipt-int*. error while compilation
}

void operation2(int * ipt) //2+(*ipt) - as for me this one match to
your question
{
& int a=2;
a+=*ipt; //a=12, n does not change
}

void operation3(int * ipt) //(*ipt)+2
{
int a=2;
*ipt+=a; //n=12, a does not change (a=2)
}

void main()
{
int n=10;
operation1(&n);
operation2(&n);
operation3(&n);
}
