A program that executes in c but not in c plus plus?

Answer 1

The logic to create such programs is very simple. We know that rules of programming languages. Among them the most important one is "We should not use keywords as identifiers". Based on this rule we can create many programs that execute in c but not in cpp. Suppose write a program to and two numbers. Store the two values in two variables, name the variables as class and object. then execute in c. it will produce the output, and do the same thing in cpp, it will give two errors. because we used keywords as identifiers in cpp.

ex:-#include<stdio.h>

#include<conio.h>

void main()

{

int class=10,object=26,res;

res=class+object;

printf("%d",res);

getch();

}

Or:

char str3[3] = "ABC"; /* doesn't compile in C */
