The function ispunct() is used to check that the passing character is a punctuation or not. It returns zero, if it is not a punctuation, otherwise it returns a non-zero value.Here is the syntax of ispunct() in C language, int ispunct(int character);Here is an example of ispunct() in C language, Example Live Demo#include #include int main() { int a = '!'; int b = 'a'; if(ispunct(a)) printf("The character is a punctuation."); else printf("The character is not a punctuation."); if(ispunct(b)) printf("The character is a punctuation."); else printf("The character is not a ...

The function fflush(stdin) is used to flush the output buffer of the stream. It returns zero, if successful otherwise, returns EOF and feof error indicator is set.Here is the syntax of fflush(stdin) in C language,int fflush(FILE *stream);Here is an example of fflush(stdin) in C language,Example Live Demo#include #include int main() { char s[20] = "Helloworld"; printf("The string : %s", s); fflush(stdin); return 0; }OutputThe string : Helloworld
rand()The function rand() is used to generate the pseudo random number. It returns an integer value and its range is from 0 to rand_max i.e 32767.Here is the syntax of rand() in C language, int rand(void);Here is an example of rand() in C language, Example Live Demo#include #include int main() { printf("%d", rand()); printf("%d", rand()); return 0; }Output1804289383 846930886srand()The function srand() is used to initialize the generated pseudo random number by rand() function. It does not return anything.Here is the syntax of srand() in C language, void srand(unsigned int number);Here is an example of srand() in C ... Read More
The swap() function is used to swap two numbers. By using this function, you do not need any third variable to swap two numbers.Here is the syntax of swap() in C++ language, void swap(int variable_name1, int variable_name2);If we assign the values to variables or pass user-defined values, it will swap the values of variables but the value of variables will remain same at the actual place.Here is an example of swap() in C++ language, Example Live Demo#include using namespace std; int main() { int x = 35, y = 75; printf("Value of x :%d", x); printf("Value of ...

The CHAR_BIT is the number of bits in char. It is declared in “limits.h” header file in C++ language. It is of 8-bits per byte.Here is an example of CHAR_BIT in C++ language,Example Live Demo#include using namespace std; int main() { int x = 28; int a = CHAR_BIT*sizeof(x); stack s; cout
The new operatorThe new operator requests for the memory allocation in heap. If the sufficient memory is available, it initializes the memory to the pointer variable and returns its address.Here is the syntax of new operator in C++ language, pointer_variable = new datatype;Here is the syntax to initialize the memory, pointer_variable = new datatype(value);Here is the syntax to allocate a block of memory, pointer_variable = new datatype[size];Here is an example of new operator in C++ language, Example#include using namespace std; int main () { int *ptr1 = NULL; ptr1 = new int; float *ptr2 = new ...

You can try to run the following code to add space between pagination links with CSS:ExampleLive Demo .demo { display: inline-block; } .demo a { color: red; padding: 5px 12px; text-decoration: none; transition: background-color 2s; border: 1px solid orange; } .demo a.active { background-color: orange; color: white; border-radius: 5px; } .demo a:hover:not(.active) { background-color: yellow; } .demo a:first-child { border-top-left-radius: 10px; border-bottom-left-radius: 10px; } .demo a:last-child { border-top-right-radius: 10px; border-bottom-right-radius: 10px; } Our Quizzes
The ceil FunctionThe ceil function returns the smallest possible integer value which is equal to the value or greater than that. This function is declared in “cmath” header file in C++ language. It takes single value whoes ceil value is to be calculated. The datatype of variable should be double/float/long double only.Here is the syntax of ceil function in C++ language, double ceil(double x); float ceil(float x);Here is an example of ceil function in C++ language, Example Live Demo#include #include using namespace std; int main() { float var = 1234.25; float res; res = ceil(var); ...

The const member functions are the functions which are declared as constant in the program. The object called by these functions cannot be modified. It is recommended to use const keyword so that accidental changes to object are avoided.A const member function can be called by any type of object. Non-const functions can be called by non-const objects only.Here is the syntax of const member function in C++ language, datatype function_name const();Here is an example of const member function in C++, Example Live Demo#include using namespace std; class Demo { int val; public: Demo(int x = 0) { ...

atol() FunctionThe function atol() converts string into a long integer. It returns zero, when no conversion is performed. It returns the converted long int value.Here is the syntax of atol in C++ language,long int atol(const char *string)Here is an example of atol() in C++ language,Example Live Demo#include using namespace std; int main() { long int a; char str[20] = "538756"; a = atol(str); cout
