C Program to Find Smallest Number in an Array

Prerequisites

Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
For loop in C programming.

Arithmetic operations in C Programming.

What is An array?

The array is a collection of similar data types. An array can store multiple values with different indexes in memory by using a single variable. The array can be both single as well as multidimensional.

Find the Smallest Number in an Array.

In this program, First, we will first take the size of the array from the user. Then we will take the elements of the array from the user. After that, we will compare every element of the array and Find the Smallest Number in an Array. Then we will print the result smallest element of the array to the user.

With the help of this program, we can be Find the Smallest Number in an Array.

Program Code:-

/* C Program to Find Smallest Number in an Array */
#include<stdio.h>
 
int main() 
{
    //declaring the variables for the program.
   int a[30], i, no, smll;
   //a[30] = it will hold the integer elements of the array.
   //i = it will hold the integre value for the loop.
   //no = it wii hold the input number of elements of the array.
   //smll = it wii hold the smallest element of the array.
   
   //taking the number of elements of the array.
   printf("\nEnter no of elements :");
   scanf("%d", &no);
 
   //Read number of elements in an array
   for (i = 0; i < no; i++)
      scanf("%d", &a[i]);
 
   //Consider first element as smallest
   smll = a[0];
 
   for (i = 0; i < no; i++) {
      if (a[i] < smll) {
         smll = a[i];
      }
   }
 
   // Printing out the smallest element of the array in Result
   printf("\nSmallest Element of the array : %d", smll);

   return (0);
}

/* C Program to Find Smallest Number in an Array */

#include<stdio.h>

int main()

{

//declaring the variables for the program.

int a[30], i, no, smll;

//a[30] = it will hold the integer elements of the array.

//i = it will hold the integre value for the loop.

//no = it wii hold the input number of elements of the array.

//smll = it wii hold the smallest element of the array.

//taking the number of elements of the array.

printf("\nEnter no of elements :");

scanf("%d", &no);

//Read number of elements in an array

for (i = 0; i < no; i++)

scanf("%d", &a[i]);

//Consider first element as smallest

smll = a[0];

for (i = 0; i < no; i++) {

if (a[i] < smll) {

smll = a[i];

}

// Printing out the smallest element of the array in Result

printf("\nSmallest Element of the array : %d", smll);

return (0);

}

Output:-

In the above program, we have first initialized the required variable.

no = it will hold the integer value.
i = it will hold the integer value.
a[30] = it will hold the integer value.

smll = it will hold the integer value.

Taking the size of the array and the elements.

Program Code to find the smallest elements in the array.

Printing output of the program.
