fseek() in C language, is use to move file pointer to a specific position. Offset and stream are the destination of pointer, is given in the function parameters. If successful, it returns zero. If it is not successful, it returns non-zero value.Here is the syntax of fseek() in C language, int fseek(FILE *stream, long int offset, int whence)Here are the parameters used in fseek()stream − This is the pointer to identify the stream.offset − This is the number of bytes from the position.whence − This is the position from where offset is added.whence is specified by one of the following ...

In C language, ftell() returns the current file position of the specified stream with respect to the starting of the file. This function is used to get the total size of file after moving the file pointer at the end of the file. It returns the current position in long type and file can have more than 32767 bytes of data.Here is the syntax of ftell() in C language, long int ftell(FILE *stream)Here is the parameter used in ftell(), stream − This is the pointer to a FILE object that identifies the stream.Here is an example of ftell() in C ...

Register variables tell the compiler to store the variable in CPU register instead of memory. Frequently used variables are kept in registers and they have faster accessibility. We can never get the addresses of these variables. “register” keyword is used to declare the register variables.Scope − They are local to the function.Default value − Default initialized value is the garbage value.Lifetime − Till the end of the execution of the block in which it is defined.Here is an example of register variable in C language, Example Live Demo#include int main() { register char x = 'S'; register int ...

The sinh() function returns the hyperbolic sine of an angle given in radians. It is an inbuilt function in C++ STL.The syntax of the sinh() function is given as follows.sinh(var)As can be seen from the syntax, the function sinh() accepts a parameter var of data type float, double or long double. It returns the hyperbolic sine of var.A program that demonstrates sinh() in C++ is given as follows.Example Live Demo#include #include using namespace std; int main() { double d = 5, ans; ans = sinh(d); cout
The operators, which require three operands to act upon, are known as ternary operators. It can be represented by “ ? : ”. It is also known as conditional operator. The operator improves the performance and reduces the line of code.Here is the syntax of ternary operator in C language, Expression1 ? Expression2 : Expression3Here is an example of Ternary Operators in C language, Example Live Demo#include int main() { int a = -1; double b = 26.4231; int c = a? printf("True value : %lf", b):printf("False value : 0"); return 0; }OutputTrue value : 26.423100Expression1 ...

The cosh() function returns the hyperbolic cosine of an angle given in radians. It is an inbuilt function in C++ STL.The syntax of the cosh() function is given as follows.cosh(var)As can be seen from the syntax, the function cosh() accepts a parameter var of data type float, double or long double. It returns the hyperbolic cosine of var.A program that demonstrates cosh() in C++ is given as follows −Example Live Demo#include #include using namespace std; int main() { double d = 5, ans; ans = cosh(d); cout
The atanh() function returns the arc hyperbolic tangent or the inverse hyperbolic tangent of an angle given in radians. It is an inbuilt function in C++ STL.The syntax of the atanh() function is given as follows.atanh(var)As can be seen from the syntax, the function atanh() accepts a parameter var of data type float, double or long double. The value of this parameter should be between -1 and 1. It returns the arc hyperbolic tangent of var.A program that demonstrates atanh() in C++ is given as follows.Example Live Demo#include #include using namespace std; int main() { double d = ...

Increment operators are used to increase the value by one while decrement works opposite increment. Decrement operator decreases the value by one.Here is the syntax of pre-increment operator in C language, ++variable_name;Here is the syntax of pre-decrement operator in C language, --variable_name;Let us see the difference between pre-increment and pre-decrement operator.Pre-increment − Before assigning the value to the variable, the value is incremented by one.Here is an example of pre-increment in C language, Example Live Demo#include int main() { int i = 5; printf("The pre-incremented value : %d", i); while(++i < 10 ) printf("%d\t", i); ...

The tanh() function returns the hyperbolic tangent of an angle given in radians. It is an inbuilt function in C++ STL.The syntax of the tanh() function is given as follows.tanh(var)As can be seen from the syntax, the function tanh() accepts a parameter var of data type float, double or long double. It returns the hyperbolic tangent of var.A program that demonstrates tanh() in C++ is given as follows.Example Live Demo#include #include using namespace std; int main() { double d = 5, ans; ans = tanh(d); cout
The acosh() function returns the arc hyperbolic cosine or the inverse hyperbolic cosine of an angle given in radians. It is an inbuilt function in C++ STL.The syntax of the acosh() function is given as follows.acosh(var)As can be seen from the syntax, the function acosh() accepts a parameter var of data type float, double or long double. The value of this parameter should be greater than or equal to 1. It returns the arc hyperbolic cosine of var.A program that demonstrates acosh() in C++ is given as follows.Example Live Demo#include #include using namespace std; int main() { double ... Read More
