Whats wrong with this?
Hey I just started learning C++ today and am already encountering problems. I recently wrote this program:
#include <iostream>
#include <cmath>
int main() {
using namespace std;
double a;
a = sqrt(5);
cout << a;
system ("pause")
Return 0;
}
But whenever I try to compile it just says:
C:\Dev-Cpp\Untitled5.cpp
[Warning] In function `int main()':
What am I doing wrong?
#include <iostream>
#include <cmath>
int main() {
using namespace std;
double a;
a = sqrt(5);
cout << a;
system ("pause")
Return 0;
}
But whenever I try to compile it just says:
C:\Dev-Cpp\Untitled5.cpp
[Warning] In function `int main()':
What am I doing wrong?
no Return --->return
put ; after system ("pause")
put using namespace std before int main
sqrt is float function you should write 5.0
#include <iostream>
#include <cmath>
using namespace std;
int main() {
double a;
a = sqrt (5.0);
cout << a;
system ("pause");
return 0;
}
put ; after system ("pause")
put using namespace std before int main
sqrt is float function you should write 5.0
#include <iostream>
#include <cmath>
using namespace std;
int main() {
double a;
a = sqrt (5.0);
cout << a;
system ("pause");
return 0;
}
