Want to convert these C++ to C??

Code:#include <iostream.h> #include <iomanip.h> // Print out the first n Fibonacci numbers. n is assumed to be >= 1. void fibo ( int n ) { int current = 1; // The value of the (i)th fibonacci number int next = 1; // The value of the (i+1)th fibonacci number cout << "\n\n\t I \t Fibonacci(I) \n\t=====================" << endl; for ( int i = 1; i <= n; i++ ) { cout << "\t" << setw(3) << i << "\t\t" << setw(4) << current << endl; int next2 = current + next; current = next; next = next2; } } int main ( void ) { int n; // The number of fibonacci numbers we will print cout << "How many Fibonacci numbers do you want to compute? "; cin >> n; if ( n <= 0 ) cout << "The number should be positive." << endl; else fibo ( n ); return 0; } #include <iostream.h> /* Get a positive integer from user */ int getPositive(void){ int current; while( 1 ){ cout << "Please enter a positive integer: "; cin >> current; if (current > 0) return current; cout << "It should be a positive integer"; } } /* Compute GCD */ int gcd (int dividend, int divisor) { int remaind; remaind = dividend % divisor; while (remaind != 0) { dividend = divisor; divisor = remaind; remaind = dividend % divisor; } return divisor; } void main(void) { int dividend = getPositive(); int divisor = getPositive(); cout << "The GCD of " << dividend << " and " << divisor << " is " << gcd(dividend, divisor) << endl; }
