###### One Dimensional Array - Question 3

In this question, we will see how to input 10 numbers in a one dimensional integer array and find the position of the largest and the smallest number in C programming. To know more about one dimensional array click on the one dimensional array lesson.

**Q3)** Write a program in C to input 10 numbers in a one dimensional integer array and find the position of the largest and the smallest number.

#### Program

```
#include <stdio.h>
#include <conio.h>
int main()
{
int a[10], i,ln,lnp,sn,snp;
printf("Enter 10 numbers\n");
for(i=0; i<10; i++)
{
scanf("%d",&a[i]);
}
for(i=0; i<10; i++)
{
if(i==0)
{
ln=a[i];
sn=a[i];
lnp=i;
snp=i;
}
else if(a[i]>ln)
{
ln=a[i];
lnp=i;
}
else if(a[i]<sn)
{
sn=a[i];
snp=i;
}
}
printf("Largest Number Position = %d\n",lnp+1);
printf("Smallest Number Position = %d\n",snp+1);
return 0;
}
```

#### Output

Enter 10 numbers 63 12 57 61 98 11 3 4 75 82 Largest Number Position = 5 Smallest Number Position = 7
