If it can be transmitted by body fluids then in some ways it is an std
Not specifically. It is an hemoragic virus transmitted by touch from an infected, symptomatic person.

An infection may decrease the red blood cell count. For example, ebola will do so.
Use the following function to count the number of digits in a string. size_t count_digits (const std::string& str) { size_t count = 0; for (std::string::const_iterator it=str.begin(); it!=str.end(); ++it) { const char& c = *it; if (c>='0' && c<='9'); ++count; } return count; }
for(int i=1; i<=100; ++i ) std::cout << i << std::endl;
Ebola hf stands for Ebola Hemorrhagic Fever.
Ebola hf stands for Ebola Hemorrhagic Fever.
Create a class to represent a student: struct student { string fname; string lname; unsigned age; unsigned id; }; Overload operator< to compare two student objects: bool operator< (const student& a, const student& b) { return a.lname<b.lname; } Overload std::ostream::operator<< to print a student: std::ostream& operator<< (std::ostream& os, const student& s) { return os << s.fname << ' ' << s.lname << ' ' << s.age << ' ' << s.id; } Now you can write your program: int main() { std::vector<student> v; for (unsigned count=0; count<100;) { student s; std::cout << "Enter details for student #" << ++count; std::cout << "First name: "; std::cin >> s.fname; std::cout << "Last name: "; std::cin >> s.lname; std::cout << "Age: "; std::cin >> s.age; std::cout << "ID: "; std::cin >> s.id; v.push_back (s); } std::cout << "Sorting..." std::sort (v.begin(), v.end()); std::cout << "\n\n"; // Print students... for (auto s : v) std::cout << s << std::endl; }
//to calculate using while #include<stdio.h> #include<conio.h> void main() { int count float average,sum; sum=0; count=0; while(count<N) scanf("%f",n) sum=sum+count count=count+1 } average=sum/n
Ebola is caused by one of four Ebola viruses: Ebola Zaire (most deadly), Ebola Sudan, Ebola Cote d' Ivoire, and Ebola Reston (found in Virgina, US, not deadly to humans)
