### dnt nw what i am doing wrong

#include <iostream>
#include <cmath>
using namespace std;

int main()
{
// The value of pressure in pounds per square inch of a wareform;
const double Time= 35;
int t,psi;

cout << " nEnter time by user:";
if
(time <= 35);

"pressure" 0.46 t psi;

else
(time >= 35)
pressure is 0.19 t + 9.45 psi;

count << "The pressure in psi and time in t" << pressure << endl;

return 0 ;
}
use [/CODE] tags pls.

there's lots of brackets missing...look up how to do control statements in C++
'else' isn't used that way

'count' is probably a typo..

makes no sense:
`pressure is 0.19 t + 9.45 psi;`
maybe u want this?
`pressure = 0.19 * t + 9.45 * psi;`
but that doesn't matter much because psi and t are not initialized...
look up 'cin' which is 'cout's best friend XD
thank u soranz i tried the other way is this correct but the only 1 error is showing up is the 19 expected `;' before string constant what shall i do
#include <iostream>
#include <cmath>
using namespace std;

int main()
{
// The value of pressure in pounds per square inch of a wareform;
const double Time= 35;
int t,psi;

cout << " nEnter time by user:";
{
if (t <= 35)
cout << 'pressure' << (0.46) << "psi";
}
{

(t >= 35)
"cout" << 'pressure' << (0.19 + 9.45) << "psi";
}
cout << "The pressure in psi and time in t" << pressure << endl;

system("PAUSE");
return 0 ;
i hope u can help me with this. plis
`"cout" << 'pressure' << (0.19 + 9.45) << "psi";`

Why is `cout` enclosed in quotation marks ?
If this compiles u should trash ur compiler...
I'm just going to point to things that need to be fixed...
First, codetags like so:
 ``123456789101112131415161718192021222324252627282930`` ``````#include #include using namespace std; int main() { //dont need ; in comments // The value of pressure in pounds per square inch of a wareform; const double Time= 35; int t,psi; cout << " nEnter time by user:"; //'n' wont produce a newline by itself. it needs the escape character... { //is cout a control statement ? if (t <= 35) //yes, 'if' is a control statement //this isn't how 'cout' works...and is not even consistent with the other one cout << 'pressure' << (0.46) << "psi"; //this is the only line that will be executed when the condition is met } { //brackets control the flow but there's nothing to control this block of code //so it will always execute - making the bracket redundant... (t >= 35) //what is the purpose of this ? "cout" << 'pressure' << (0.19 + 9.45) << "psi"; //how is cout used ? } //and this one too //this is a good cout tho u might want an extra space after 't' for readability cout << "The pressure in psi and time in t" << pressure << endl; system("PAUSE"); return 0 ; //good end //what's missing here ? ``````

It looks like u also want to add functionality for user input. This can be accomplished with 'cin'. Where cout prints things out to the screen, cin takes inputs from a user which can be stored, manipulated and then printed out to the screen again using cout.
