Read MoreAssigning multiple characters in an int in C language
The character type data is stored by its ASCII value internally in C or C++. If we want to print a single character as integer, we will get the ASCII value. But when we are trying to print more than one character using a single quote, then it will print some strange output.Please check the following program to get the idea.Example#include int main() { printf("%d", 'A'); printf("%d", 'AA'); printf("%d", 'ABC'); }Output65 16705 4276803The ASCII of A is 65. So at first it is showing 65 (01000001). Now for AA, it is showing 16705. This is ASCII ...

The tag will make the specified bundle available to all tags that occur between the bounding and tags. With this, you need not specify the resource bundle for each of your tags.For example, the following two blocks will produce the same output − AttributeThe tag has the following attributes −AttributeDescriptionRequiredDefaultbasenameSpecifies the base name of the resource bundle that is to be loaded.YesNonePrefixValue to prepend to each key name in subtagsNoNoneExampleResource bundles contain locale-specific objects. Resource bundles contain key/value pairs. When your program ...
Read MoreC++ Program to Search Sorted Sequence Using Divide and Conquer with the Aid of Fibonacci Numbers
In this C++ program we implement a Divide and Conquer approach using Fibonacci numbers. Using Fibonacci numbers, we calculate mid of data array to search the data item. The time complexity of this approach is O(log(n)).AlgorithmBegin Assign the data to the array in a sorted manner. Take input of the element to be searched. Call FibonacciSearch() function. Calculate the mid value using ‘start+fib[index-2]’ expression. If the chosen item is equal to the value at mid index, print result and return to main. If it is lesser than the value at mid index, proceed with ...

Read MoreOperations on struct variables in C
Here we will see what type of operations can be performed on struct variables. Here basically one operation can be performed for struct. The operation is assignment operation. Some other operations like equality check or other are not available for stack.Example#include typedef struct { //define a structure for complex objects int real, imag; }complex; void displayComplex(complex c){ printf("(%d + %di)", c.real, c.imag); } main() { complex c1 = {5, 2}; complex c2 = {8, 6}; printf("Complex numbers are:"); displayComplex(c1); displayComplex(c2); }OutputComplex numbers are: (5 + 2i) (8 + 6i)This works fine as ...
