C++ Program to take out integer from comma separated string
Suppose we have a string where we have few integers which are separated by comma. We shall have to separate them out and display each integer in different line. To do this we shall use stringstream (under sstream library) in C++. This is one string based stream class present in C++. We can use extraction operator () to insert something and str() functions to set contents of underlying string device object.So, if the input is like s = "56, 9, 85, 256, 47", then the output will be56 9 85 256 47To solve this, we will follow these steps −Define ...
Read MoreC++ program to reverse an array elements (in place)
Suppose we have an array with n different elements. We shall have to reverse the elements present in the array and display them. (Do not print them in reverse order, reverse elements in place).So, if the input is like n = 9 arr = [2, 5, 6, 4, 7, 8, 3, 6, 4], then the output will be [4, 6, 3, 8, 7, 4, 6, 5, 2]To solve this, we will follow these steps −for initialize i := 0, when i < quotient of n/2, update (increase i by 1), do:temp := arr[i]arr[i] := arr[n - i - 1]arr[n - ...
Read MoreC++ program to find addition and subtraction using function call by address
Suppose we have two numbers a and b. We shall have to define a function that can calculate (a + b) and (a - b) both. But using a function in C++, we can return at most one value. To find more than one output, we can use output parameters into function arguments using pointers, and call that function using addresses of those variables. Here in this problem we shall update a with a+b and b with a-b. When we call the function we shall have to pass the address of these two variables.So, if the input is like a ...
Read MoreC++ program to find greatest among four input integers
Suppose we have four integers a, b, c and d. We shall have to find the greatest number among them by making our own function. So we shall create one max() function that takes two numbers as input and finds the maximum, then using them we shall find maximum of all four numbers.So, if the input is like a = 75, b = 18, c = 25, d = 98, then the output will be 98.To solve this, we will follow these steps −define a function max(), this will take x and yreturn maximum of x and ytake four numbers ...
Read MoreC++ program to convert all digits from the given range into words
Suppose we have two digits a and b. We shall have to convert each digit into words and print them one by one. Printing digits into words means for a digit 5, it should print "Five".So, if the input is like a = 2, b = 6, then the output will beTwo Three Four Five SixTo solve this, we will follow these steps −if d < 0 and d > 9, then:return ("Beyond range of 0 - 9")otherwise when d is same as 0, then:return ("Zero")otherwise when d is same as 1, then:return ("One")otherwise when d is same as 2, ...
Read MoreC++ program to convert digits to words using conditional statements
Suppose we have a digit d, we shall have to convert it into words. So if d = 9, our output should be "Nine". If we provide some d which is beyond the range of 0 and 9, it will return appropriate output.So, if the input is like d = 3, then the output will be "Three".To solve this, we will follow these steps −Define a function solve(), this will take d, if d < 0 and d > 9, then:return ("Beyond range of 0 - 9")otherwise when d is same as 0, then:return ("Zero")otherwise when d is same as ...
Read MoreC++ program to take integer and float as input and return their sum
Suppose we have two numbers a and b, a is integer and b is a float. We shall have to take them from standard input and display the sum.So, if the input is like a = 10 b = 56.23, then the output will be Sum: 66.23To solve this, we will follow these steps −To display output into the standard output device we can use extraction operator ()ExampleLet us see the following implementation to get better understanding −#include using namespace std; int main(){ int a; float b; cout a >> b; cout
Read MoreAngularJS – ng-blur Directive
The ng-blur Directive in AngularJS is fired when an element loses focus from that element. The blur event is executed synchronously along with the DOM manipulations (like removing from the focus point).AngularJS also executes the expression using scope.$evalAsync if the event is fired during an $apply to ensure the consistent application state.Syntax..Content..Example 1 − ng-blur DirectiveCreate a file "ngBlur.html" in your Angular project directory and copy-paste the following code snippet. ngBlur Directive Welcome to Tutorials Point ...

Sometimes we may need to represent a name or a string in capital letters. To convert a string into uppercase in AngularJS, we can use the uppercase filter to change its case to uppercase.SyntaxIn HTML Template Binding{{uppercase_expression | uppercase}}In JavaScript$filter('uppercase')()Example − Conversion to Upper CaseCreate a file "uppercase.html" in your Angular project directory and copy-paste the following code snippet. uppercase Filter Welcome to Tutorials Point AngularJS | UpperCase Filter ...
Read MoreAngularJS – angular.isArray() Function
The angular.isArray() function in AngularJS basically checks if a reference is an Array or not. This method will return True if the reference passed inside the function is an Array type, else it will return False.Syntaxangular.isArray(value)Example − Check if the reference is an Array or notCreate a file "isArray.html" in your Angular project directory and copy-paste the following code snippet. angular.isArray() Welcome to Tutorials Point AngularJS | angular.isArray() ...
