I am trying to write a code for a project, and in my if else
statements I want to put that the SWI is greater than or equal to 305 and less than or equal to 395. How would I place those limitations in the code? I tried using <=
and >=
, but I do not think the placement is correct, and I am confused on how to fix it.
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
double T,SWI,W;
cout << "HELLO USER, PLEASE ENTER THE TEMPERATURE AND WIND SPPED TO PREDICT WEATHER FORECAST";
cin >> T, W;
SWI = 150*log10(T-49) 0.41*W 125*W/T;
if (SWI < 305);{
cout << "There is a low risk of severe thunderstorms.\n";
cout << "However, still remain indoors and keep dry until the storm passes\n";
}else if (SWI >= 305,SWI <= 395); {
cout<< "Severe thunderstorms possible.\n";
cout << "Please remain indoors and expect turbulant winds.\n";
}else if(SWI > 395);{
cout << "Severe thunderstorms imminent.\n";
cout << "Stay off the roads and avoid any tall trees, possibility of tornadoes suspected.\n";
}
return 0;
} // end program

There are too many syntactic errors. Corrected version below.
also you might need to consider a check on T
. It must be >49
else the log function gets a -ve
input.
#include <iostream>
#include <cmath>
int main()
{
using namespace std;
double T,SWI,W;
cout << "HELLO USER, PLEASE ENTER THE TEMPERATURE AND WIND SPEED TO PREDICT WEATHER FORECAST";
cin >> T;
cin >> W;
SWI = (150*log10(T-49)) (0.41*W) (125*W/T);
if (SWI < 305){
cout << "There is a low risk of severe thunderstorms.\n";
cout << "However, still remain indoors and keep dry until the storm passes\n";
}else if (SWI <= 395) {
cout<< "Severe thunderstorms possible.\n";
cout << "Please remain indoors and expect turbulent winds.\n";
}else {
cout << "Severe thunderstorms imminent.\n";
cout << "Stay off the roads and avoid any tall trees, possibility of tornadoes suspected.\n";
}
return 0;
} // end program

You have some syntactics errors. you should have something like:
if (SWI< 305){ //remove ; in every if and else
cout<< "There is a low risk of severe thunderstorms.\n";
cout << "However, still remain indoors and keep dry until the storm passes\n";
}else if (SWI<=395) { // if the execution falls in here is because SWI>=305
cout<< "Severe thunderstorms possible.\n";
cout << "Please remain indoors and expect turbulant winds.\n";
}else if(SWI > 395){
cout<< "Severe thunderstorms imminent.\n";
cout << "Stay off the roads and avoid any tall trees, possibility of tornadoes suspected.\n"; }
return 0; }
