Program 104:To find minimum and maximum of given numbers

Program 104:

```#include<stdio.h>
main()
{
int i,size,max=0,min=0;
printf("Enter size to find largest and smallest of given numbers\n");
scanf("%d",&size);
int a[size];
printf("Enter numbers in array\n");
for(i=0;i<size;i++)
{
scanf("%d",&a[i]);
}
min=a[0];
max=a[0];
for(i=0;i<size;i++)
{
if(a[i]>max)
{
max=a[i];
}
if(a[i]<min)
{
min=a[i];
}
}
printf("The largest number is %d\n",max);
printf("The smallest number is %d\n",min);
} ```
Explanation:

1. This program starts with initializing :
• i→ Helping variable
• size→Indicates size of array i.e number of elements to be stored in array
• max,min→ To Store maximum and minimum numbers from given array
• a[size]→ To store array elements of given size
2. ` printf("Enter size to find largest and smallest of given numbers\n");`
```    scanf("%d",&size);
int a[size];
printf("Enter numbers in array\n");
for(i=0;i<size;i++)
{
scanf("%d",&a[i]);
}```
Taking size and array elements as input from user
3. ```min=a[0];
max=a[0];```
Initializing min,max to first element in array.So lets take array elements say,45,30,35,32.
4. Then min=45 and max=45
5. ```for(i=0;i<size;i++)
{
if(a[i]>max)
{
max=a[i];
}
if(a[i]<min)
{
min=a[i];
}
}```
We are iterating from 1st element till last element in array.I will explain in brief since all of you by now are acquainted with for loop working.Since there are 4 elements in array 45,30,35,32.min=45,max=45. this is our intial data.
• In 1st iteration where i=0
• so a[0]=45>max which is not true since both are equal but not greater.so if part won't execute
• a[0]<min=45<min is also false
• Finally both if parts won't execute in 1st iteration
• End of Iteration 1 : min=45,max=45 no change has been made
• In 2nd iteration where i=1
• so a[1]=30>max=30>45 which is not true so if part won't execute
• a[1]<min=30<min =30<45 is true so if part will execute.Then min=a[2] --min=30
• End of Iteration 2 : min=30,max=45
• In 3rd iteration where i=2
• so a[2]=35>max=35>45 which is not true so if part won't execute
• a[2]<min=35<min =35<30 is not true so if part won't execute
• End of Iteration 3 : min=30,max=45
• In 4th iteration where i=3
• so a[3]=32>max=32>45 which is not true so if part won't execute
• a[3]<min=32<min =32<30 is not true so if part won't execute
• End of Iteration 4 : min=30,max=45
6. Finally min=30 and max=45 will be printed
