C++ program to search specific values in an array
Suppose we are given an array 'arr' that contains n number of sorted integer values. We are also given an array 'query' of size q, and we have to tell either the values in ‘query’ are present in the given array 'arr' or not. If a value in query is present in arr, we print "Present" along with the position where the value is situated in. Otherwise, we print "Not present" and print the position in arr, where the minimum value greater than the value in query is located. We have to remember that the arrays are 1-indexed.So, if the ...

Suppose we are given three double values. We have to format them and print them in the following format.We have to print the integer part of the first value in hexadecimal format with lowercase letters.We have to print the second value up to two decimal places, putting a sign before it to show whether it is positive or negative. The second value to be printed has to be rightjustified and 15 characters long, padded with underscores in the left unused positions.We have to print the third value up to nine decimal places in a scientific notation.So, if the input is ...
Read MoreC++ program to print values of different data types provided as input
Suppose we are given an integer value, a long value, a character value, a float value, and a double value as inputs. We have to print the values that are given to us as input maintaining their precision.So, if the input is like integer value = 15, long value = 59523256297252, character value = 'y', float value = 367.124, double value = 6464292.312621, then the output will be15 59523256297252 y 367.124 6464292.31262To solve this, we will follow these steps −Print the values given as input in separate lines.ExampleLet us see the following implementation to get better understanding −#include #include ...
