C++ search an array for an element 🔎

#array #search #element

C++ linear search tutorial example explained

[BroCodez]

#include<iostream>

int searchArray(std::string array[], int size, std::string element);

int main()
{
std::string foods[] = {"pizza", "hamburger", "hotdog"};
int size =
int index;
std::string myFood;

std::cout << "Enter element to search for: " << '\n';
std::getline(std::cin, myFood);

index = searchArray(foods, size, myFood);

if(index != -1){
std::cout << myFood << " is at index " << index;
}
else{
std::cout << myFood << " is not in the array";
}

return 0;
}
int searchArray(std::string array[], int size, std::string element){

for(int i = 0; i < size; i++){
if(array[i] == element){
return i;
}
}
return -1;
}

A Multiplatform GUI with c++ tutorial would be really cool. For example, the qt framework

My Assignment:

#include <iostream>

double average(double grades[], int numGrades);

int main () {

double grades[] = {93, 100, 98, 100, 100, 100};
int numGrades =
double averageGrade = average(grades, numGrades);

std::cout << "Average Grade: " << averageGrade << "\n";

return 0;
}


double average(double grades[], int numGrades) {
double averageGrade;
double total=0;
for (int i = 0; i < numGrades; i++){
total += grades[i];
}
averageGrade = total/numGrades;

return averageGrade;
}

Search for existence and index of a specific element in array of any data type

template <typename T>
int SearchArr(T arr[], int arrSize, T targ){
for (int i = 0 ; i <= arrSize-1 ; i++){
if (arr[i] == targ){
return i;
}
}
return -1;
}
