**Smallest Number in an array**

**Smallest Number in an array**

Write a C++ Program to Find the Smallest Number in an array. Here’s simple Program to Find the Smallest Number in an array in C++ Programming Language.

**What is an Array ?**

**What is an Array ?**

Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.

To find the smallest number in an array in C++ programming, you have to ask to the user to enter the array size and array elements, now start finding for the smallest element in the array to display the smallest element of the array

Here is source code of the C++ Program to Find the Smallest Number in an array. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

**SOURCE CODE : :**

**SOURCE CODE : :**

/* C++ Program to Find the Smallest Number in an array */ #include<iostream> using namespace std; int main() { int small, arr[50], m, j; cout<<"Enter size of Array ( Max:50 ) :: "; cin>>m; cout<<"\nEnter Elements to Array Below :: \n"; for(j=0;j<m;++j) { cout<<"\nEnter arr["<<j<<"] Element :: "; cin>>arr[j]; } cout<<"\nSearching for smallest element ...\n\n"; small=arr[0]; for(j=0; j<m; j++) { if(small>arr[j]) { small=arr[j]; } } cout<<"Smallest Element in Array = "<<small<<"\n"; return 0; }

**OUTPUT : :**

**OUTPUT : :**

/* C++ Program to Find the Smallest Number in an array */ Enter size of Array ( Max:50 ) :: 8 Enter Elements to Array Below :: Enter arr[0] Element :: 0 Enter arr[1] Element :: 3 Enter arr[2] Element :: 5 Enter arr[3] Element :: 1 Enter arr[4] Element :: 8 Enter arr[5] Element :: 5 Enter arr[6] Element :: 3 Enter arr[7] Element :: 9 Searching for smallest element ... Smallest Element in Array = 0 Process returned 0

Above is the source code for C++ Program to Find the Smallest Number in an array which is successfully compiled and run on Windows System.The Output of the program is shown above .

**Thanks for reading the post….**

I have the part where it finds the smallest element (in relation to my problem), but instead of just outputting the smallest element; it’s outputting the process of finding the smallest (if it isn’t the first element).

#include <iostream>

using namespace std;

int main() {

int ages[5];

int n = ages[0];

for (int i = 0; i < 5; ++i) {

cin >> ages[i];

if (n > ages[i]){

n = ages[i];

cout << n << endl;

}

}

return 0;

}

-I also used the program as stated in the solution but with no success.
