Finding smallest value in an array is a classic C array program. This program gives you an insight of iteration, array and conditional operators. We iteratively check each element of an array if it is the smallest. See the below program.

## Algorithm

Let's first see what should be the step-by-step procedure of this program −

```START
Step 1 → Take an array A and define its values
Step 2 → Declare smallest as integer
Step 3 → Set smallest to 0
Step 4 → Loop for each value of A
Step 5 → If A[n] < smallest, Assign A[n] to smallest
Step 6 → After loop finishes, Display smallest as smallest element of array
STOP
```

## Pseudocode

Let's now see the pseudocode of this algorithm −

```procedure smallest_array(A)

Declare smallest as integer
Set smallest to 0
FOR EACH value in A DO
IF A[n] is less than smallest THEN
smallest ← A[n]
ENDIF
END FOR
Display smallest

end procedure
```

## Implementation

This pseudocode can now be implemented in the C program as follows −

```#include <stdio.h>

int main() {
int array[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0};
int loop, smallest;

smallest = array[0];

for(loop = 1; loop < 10; loop++) {
if( smallest > array[loop] )
smallest = array[loop];
}

printf("Smallest element of array is %d", smallest);

return 0;
}
```

The output should look like this −

```Smallest element of array is 0
```
