The compiler error message should have explained you the issue in the first place
Богдан
Read those in terminal if you compile via terminal, or in tool windows in your IDE if you use one

it says in the error that no matching function for call to 'Triangle::Area_Tri()' can someone help me fix this
jaebie
#include<iostream>
using namespace std;
class Triangle
{
public:
double Area, Peri, Angle;
void Area_Tri(double h,double b)
{
height = h;
base = b;
Area = ((b*h)*(0.5));
}
void Peri_Tri(double j, double b, double m)
{
side1 = j;
side2 = b;
side3 = m;
Peri = j+b+m;
}
void Angle_Tri(double ang)
{
if(ang<90)
std::cout<<"The triangle is an acute-angled.";
if(ang==90)
std::cout<<"The triangle is a right-angled.";
if(ang>90)
std::cout<<"The triangle is an obtuse-angled.";
}
private:
double height,base,side1,side2,side3;
};
int main()
{
Triangle triangle1;
triangle1.Area_Tri(4,6);
std::cout<<"The area of the triangle is "<< triangle1.Area_Tri()<<".";
return 0;
}
jaebie
here's the code
jaebie
Should I change them to float or int?
jaebie
double
jaebie
the area of the triangle
jaebie
still error :(
jaebie
it says here no matching function for call to 'Triangle::Area_Tri(double&)'
jaebie
Error lol
jaebie
still the same
jaebie
its now working, thank you very much
jaebie
what would be the problem in the code if a random scientific notation occured at the end of the program?

Hi guys i want to ask, here is my code:
class CarWash {
public:
string jenisLayanan;
string status;
double discount;
public:CarWash() {
cout<<"Welcomeeeee" << "\n";
}
public:void setValue(string j, string s, double d) {
jenisLayanan = j;
status = s;
discount = d;
}
virtual int hitungHarga() {return 0;};
};
class CuciMobil:public CarWash{
public:int hitungHarga() {
return 75000 - (75000 * discount);
}
};
class VacumInterior:public CarWash{
public:int hitungHarga() {
return 50000 - (50000 * discount);
}
};
class CuciBagianBawah:public CarWash{
public:int hitungHarga() {
return 150000 - (150000 * discount);
}
};
Why the base class (CarWash) constructor is called 3 times? how to call it once?
Thanks
Talula
Dafa Pramudya
Because it is inherited... it depends on which constructor you want to call...
It's possible to called once ? (base constructor)
Talula
It's possible to called once ? (base constructor)
Technically I don't know how it is done... but logically I would have a variable that would be made true in the base and if it is true, it'll not return the value but if it is false it will return the value it is returning.

Graphics design definitely requires a dedicated GPU and the bigger the better. None of those boxes seem particularly suitable. The T440 is definitely not good enough, the one with 6GB of RAM doesn't have enough (but that can be fixed), the last one may be OK (?) but the tiny ass screen and tiny GPU will make it very hard

Guys

The strtof function is separing the integer part from the decimal part of my number
Same thing with the atof function
Pablo
I pass to it like "4.654" and it returns me 4
And puts .654 in the second string

If you have a char c = "x4ey3";
How do you extract each integer and make them as integer data type each one??
SLC
i can extract the integer from character but i can't make each integer to integer data type
SLC
atoi is use fro character to integer but it work char c = '4;
SLC
cout« atoi(c) it will give you integer 4

Try this ar[i] = int(c[i])-'0'

i am not getting the right result

i am not getting the right result
Why did you declare void pointer as return type and returning nothing?

#include <stdio.h>
void *str_rev(char *str);

rev[j] = str[i];
i--;
}
rev[j] = '\0';
printf("%s", rev);
}
i--; in last loop. Why you need this?
Mr. O
I am getting half of the result instead of full result
`` 🇫🇷 ;; ce serai ta blonde ce soir, si c'est ce que tu aimes
The fact that you have at least some result is a miracle
`` 🇫🇷 ;; ce serai ta blonde ce soir, si c'est ce que tu aimes
So, you can delete the first for loop because C has strlen function
Mr. O
I want the reverse of the input
Mr. O
Yes
`` 🇫🇷 ;; ce serai ta blonde ce soir, si c'est ce que tu aimes
So, you can delete the first for loop because C has strlen function
And if you just want to print reversed string you can do
for (size_t i = strlen(str) - 1; i; --i) {
putchar(str[i]);
}
putchar('\n');
