C Exercises: Lowest value and position within an array

C Basic Declarations and Expressions: Exercise-130 with Solution

Write a C program to create an array of length n and fill the array elements with integer values. Find the smallest value and its position in the array.

Sample Solution:

C Code:

#include <stdio.h>
int main ()
{
  int array_size, i, x, z;
  int min_val, position;

  // Prompt the user for the array size
  printf("Input the array size:\n");
  scanf("%d", &array_size);

  // Declare an array of integers with the specified size
  int vetor[array_size];

  // Prompt the user to input array elements
  printf("\nInput array elements:\n");
  for (i = 0; i < array_size; i++)
  {
    scanf("%d", &z);
    vetor[i] = z; // Store the input value in the array
  }

  // Initialize min_val and position with the first element of the array
  min_val = vetor[0];
  position = 0;

  // Loop to find the smallest value and its position within the array
  for (i = 1; i < array_size; i++)
  {
    if (vetor[i] < min_val)
    {
      min_val = vetor[i]; // Update the minimum value
      position = i; // Update the position of the minimum value
    }
  }

  // Print the smallest value and its position
  printf("\nSmallest Value: %d\n", min_val);
  printf("Position within array: %d\n", position);

  return 0; // End of program
}

Sample Output:

Input the array size:
5

Input array elements:
35
17
-5
45
36

Smallest Value: -5
Position within array: 2

Flowchart:

C programming Code Editor:

Previous: Write a C program that reads an array (length 10), and replace the first element of the array by a give number and replace each subsequent position of the array by one-third value of the previous.
Next: Write a C program that accepts two strings and check whether the second string present in the last part of the first string.
