you give  wrong coding i was run this code on turbo then it gives error like(/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status)

This is a function that you would have to call in main. Example
#include <stdio>

int main()
{
    cout << sumofnatural(9) <<endl;
    return 0;
}
