To search a particular element from the vector, use the find() algorithm. If the vector is sorted, you can use the binary_search() algorithm to improve efficiency. Both algorithms can be found in the <algorithm> header in the C++ standard library.

How do you write a program in c plus plus to search a number in an array?
The following function performs a non-recursive linear search of the given vector, returning a constant iterator to the element containing the given value. If the value does not exist, the "one-past-the-end" iterator is returned instead. std::vector<int>::const_iterator find (int val, const std::vector<int>& v){ for (std::vector<int>::const_iterator it=v.begin(); it!=v.end(); ++it) if (*it==val) return it; return v.end(); }
If array is full how you apply linear search?
An array in C is structured so that it has no particular size; you have to know ahead of time what the dimensions are.So, a linear search means that you go from the first element to the last, either finding the element in the table, or going to the very last element and not finding it.Arrays in C can be zero-terminated, in which case you get the element that does not have a value, and that indicates the value you are searching for is not there.If the array is not zero terminated then you can calculate the dimension of the array, or apply the sizeof operator times the size of the first element to determine the length of the search.
The contents of a particular element of an array is called?
It is the value of the element.
What algorithm uses a loop to step through each element of an array starting with the first element searching for a value?
What you're describing is called a sequential search or linear search.
How do you search for an element in unsorted array?
Let's use integers as an example. int elementToFind; // the element we want to search for int[] elementArray; // the array we want to search through boolean found = false; //boolean flag to indicate if we found the element or not for(int i = 0; i < elementArray.length; ++i) { if(elementArray[i] == elementToFind) { // we found the element at index i // do whatever you want to do with this information found = true; } //if found is still false so it means this element is not found if(!found) { //the element is not found in the array } }
What vector is created by pointing in a particular direction?
Which of the following are not vector directions?
How do you find the vector sum and vector difference of the two vector quantities?
Element by element. That is: Sum all the first elements to get the first element of the result; Sum all the second elements to get the second element of the result...The vector sum is obtained by adding the two quantities. The vector difference is obtained by subtracting one from the other. Hint: 'sum' always means addition is involved, 'difference' always means subtraction is involved.* * * * *That is the algebraic answer. There is also a geometric answer.To sum vectors a and b, draw vector a. From the tip of vector a, draw vector b. Then a + b is the vector from the base of a to the tip of b. To calculate a - b, instead of drawing b,draw the vector -b, which is a vector of the same magnitude as b but going in the opposite direction.

What is the speed of an object moving on a particular direction?
The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.
How do you find particular element in array?
by using index position we can find the particular element in array.
Which measurement is a vector quantity?
A vector quantity measures the movement of a particular object in a given direction. An example of a vector quantity is velocity.
Is work and energy scalar or vector quantities explain?
It is scalar. This simply means that - unlike vector quantities - energy is not defined in a particular direction.

What is the average of all the naturally occurring isotopes of a particular element?
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Why vector is staight not a curve?
Because a vector contains information about the direction. A direction, at any particular position is the tangent to the curve and this, by definition, must be straight.
The contents of a particular element of an array is called?
It is the value of the element.
What search begin the search with the first array element?
The search for the first array element begins at the assembly plant. As they array is being constructed, the element itself is one of the first components to be completed.
