[subanbaig]

AOA, brother if I know basic JS concepts or in other words basic programming terminologies should I start learning flutter from your flutter Bootcamp or not?

[usamarazzaq]

I oculd not find a way to find the size of data types. I kept thinking and trying to find a way on my own and first thing that came to my mind was sizeOf operator but that is not available in Dart, than i googled it and did not find anything about it ?

is it possible to find size of data type in dart?

[SuarahsAi]

assalam o alikum agian sir swappping esy b tou ki jaskti hai

double x;
double y;

x = 6;
y = 66;

/*FOR SWAPPING*/

print('before swapping ');
print(' Value of x: $x ');
print(' Value of y : $y');
print('After swapping');
print('Value of x:$y');
print('Value of y:$x');


Result: before swapping
Value of x: 6.0
Value of y : 66.0
After swapping
Value of x:66.0
Value of y:6.0

[mr-junaidk]

Sir aesa bhi karsaktay hai k koi third variable lailay empty aur us mai x ki value shift karay aur x mai phir y ki value shift karay aur aakhir mai us third variable mai shift ki gayi x ki value dubara y mai dalay code is given below void main(){
int x = 10;
int y = 20;
int temp; // Here temp is used just as an empty variable for shifting values
print("Before swapping");
print("Value of x is : $x");
print("Value of y is : $y\n");
temp = x; // temp = 10 // Value of x is shifted to temp and x becomes empty
x = y; // x = 20 // Value of y is shifted to x and y becomes empty
y = temp; // y = 10 // Value of temp is shifted to y and temp becomes empty
print("After swapping");
print("Value of x is : $x");
print("Value of y is : $y");
}

[hafizmuhammadabdullahkhan]

Assalamualaikum, sir I solved all the problems but one problem is not solved and I spent a lot of time on it which is a 'program to find the size of data type' kindly help

[AbdulMubeen-fqeu]

Write Program to Swap Values of Two Variables
int a = 2;
int b = 3;
print("before swapping");
print("value of a is:$a");
print("value of b is:$b");
print("after swapping");
int c = 5;
b = c - b;
a = c - a;
print("value of a is:$a");
print("value of b is:$b");


is this right ???

[SuarahsAi]

so far so good sir koi book bata dein jah ase concepts or clear hojaein
void main() {
print ('Jizakallah') ;
}

[aqmajeed]

Sir print('value of x : $x'); aisy q krty hain
Sir ye simple print('x'); q ni krty..

[mubashiralam]

sir how can i find the size of data type?

[hamza_tariq]

sir formula agr google sa dhekh le koea issue to ni ha ? yad ni rhty formula

[muhammadrizwan]

void main() {
int fah, cel, c, ;
double k = 5 / 9;
fah = 98; //-->Before conversion;
cel = 37;
k = 5 / 9;

print("BODY TEMP $fah");
print("BODY TEMP $cel");

/*
conversion;
subtract 32 and multiply by .5556 (or 5/9).
(32°F − 32) × 5/9 = 0°C


*/
fah = 98;
cel = 37;
k = 5 / 9;
c = (fah - cel * k) as int;
print(c);
}

[techknowledge]

Why you add $ to programs whats the concept behind it
