(Prac 1)Program to demonstrate the features of Dart language.

Convert String To Int In dart

void main() {

String strvalue = "1";

print("Type of strvalue is ${strvalue.runtimeType}");

int intvalue = int.parse(strvalue);

print("Value of intvalue is $intvalue");

// this will print data type

print("Type of intvalue is ${intvalue.runtimeType}");

}

Convert String To Double In Dart

void main() {

String strvalue = "1.1";

print("Type of strvalue is ${strvalue.runtimeType}");

double doublevalue = double.parse(strvalue);

print("Value of doublevalue is $doublevalue");

// this will print data type

print("Type of doublevalue is ${doublevalue.runtimeType}");

}

Convert Int To String In Dart

void main() {

int one = 1;

print("Type of one is ${one.runtimeType}");

String oneInString = one.toString();

print("Value of oneInString is $oneInString");

// this will print data type

print("Type of oneInString is ${oneInString.runtimeType}");

}

Convert Double To Int In Dart

void main() {

double num1 = 10.01;

int num2 = num1.toInt(); // converting double to int

print("The value of num1 is $num1. Its type is ${num1.runtimeType}");

print("The value of num2 is $num2. Its type is ${num2.runtimeType}");

}

To Print 1 To 10 Using For Loop

void main() {

for (int i = 1; i <= 10; i++) {

print(i);

}

}

Below code prints the even numbers from 1 to 10.

void main() {

for( var i = 1 ; i <= 10; i++ ) {

if(i%2==0) {

print(i);

}

}

}

Functions

void main() {

add(3,4);

}

void add(int a,int b) {

int c;

c = a+b;

print(c);

return c;

}
