#include <iostream> #include <string> using namespace std; void info(string[], double[], int&); int main () { int num; cout << "How many students you have? "; cin >> num; cout << endl; string student[num]; double score[num]; info(student, score, num); return 0; } // to do unlimited numbers of student's array.. void info (string student[], double score[], int& num) { for (int i=0; i<num; i++) { int j=1; cout << "Enter studen's name (" << j << "): "; cin >> student[i]; cout << "Enter student's score (" << j << "): "; cin >> score[i]; j++; cout << endl; } }

so that i want it to be 0 in the beginning

for (int i=0 ; i<num; i++) { cout << "Enter studen's name (" << i << "): "; cin >> student[i]; cout << "Enter student's score (" << i << "): "; cin >> score[i]; cout << endl; }

thanks a lot

What is the back ground of c,c++..

Historically? C was developed to make it easier to develop complex systems such as operationg systems and have a general purpose language that was higher level. Other higher level languages at that time where very narrow in scope. C++, from what i know bjarne wanted to have a safer version of c. But it supported object oriented programming as well, which was a new and rising concept at the time and i think greatly helped to its success. People critical towards object orientation (at the time some argued that through the abstraction there would be a too big performance loss and other arguments... ) mostly stayed with C. And it is still used for embeded systems until this day because it is "easy" to write a compiler for and has very little overhead. But thats just all out of memory and things i heared so dont quote me on any of this 😅

hey, how can I call a function 3 times with a "for" loop

Put the function call inside the loop 😂

For example Jason Turner wanted to rewrite Doom to C++ Actually it was really hard task And the only thing he did was just fixing compiler errors And after he fixed the errors, a benchmark he had ran faster than on the original version

i put inside the loop but it call only one time

this is a c++ program to get the score of students and display the lowest 2 scores but I don't why the result is wrong !!😢 please help me

If you haven't seen, this was for you

good evening i am a new member of the group :)

Hey how many are from outside India ?

When I say bgd how can some study ?

Ok for studing this subject what some body intended to do?

By this could I be matured enough to study further
