Provlima me programma se C

[Weiss]

Exw ftiaxei to parakatw programma gia na ypologisw me mia anadromiki sinartisi to x^n

 

#include <stdio.h>

 

void main()

{

int power(double num, double k);

int num,k;

printf("Dwse arithmo\n");

scanf("%d",&num);

printf("Dwse ektheti\n");

scanf("&d",&k);

printf("To apotelesma einai %d",power(num,k));

}

 

int power(double num,double k)

{

if(k = =0)

return(1);

else

return(num*power(num,k-1));

}

 

Kanei kanonika compile omws otan to trexw kai vazw times moy vazei illegal operation:/

Kamia idea ti kanw lathos?

Δουλεύει με gcc 3.3.2 και Borland C++ 5.5.1

 

Τρεις αλλαγές:

 

>
#include <stdio.h> 

int power ( double num, double k );  // 1) To protypo bghke apo e3w

int main()     // 2) Η main έγινε int
{ 
int num,k; 

printf("Dwse arithmo\n"); 
scanf("%d",&num);        

printf("Dwse ektheti\n"); 
scanf("%d",&k);               // 3) Edw prin eixe &d anti gia %d

printf("To apotelesma einai %d",power(num,k)); 

return 0;
} 

int power(double num,double k) 
{
if(k == 0 ) 
	return (1); 
else 
	return ( num * power ( num, k - 1 ) ); 
// return ( k ? num * power ( num, k -1 ) : 1 );
}

Weiss , επίσης μπορείς τα prototypes να τα βάζεις σε header files που είναι ακόμα πιο καλό ως προς το readability και όχι να τα έχεις στο main module σου.
