vector.push_back(value); In the above syntax, the term vector represents the vector to which we have to add elements. This function contains only one parameter, which is the value parameter as seen above, and is utilized to specify the value that needs to be pushed inside at the back ...
vtr.push_back(i); } //variable to store the vector size int s = vtr.size() ; //print the vector size cout <<"The vector size is: " << s ; return 0; } Output: An empty vector is declared in this program, and elements are added to it using a for a loop. Then, the size...
those structs in one of the vectors, the change will be reflected in the other vector as well. If you do a deep copy then the second vector will have pointers to different structs than the first vector, but those new structs will be initialized with the contents of the structs in...

C++ STL | reversing vector elements: Here, we are going to learn how to reverse elements of a vector using C++ STL program?
Construct an empty array to store the final result of the vector addition. Loop through the caller array. Use the loop index to add the caller array and the called array elements. Push the result into the empty array created from Step 1. So, it is no longer empty because it has the ...
