37.array examples for loop

The first element a[0] is considered as both "min" and "max".

We will select element by element from the second element to n-1 (a[i])

If a[i] is less than "min" then it is stored in "min"

If a[i] is greater then "max" then it is store in "max"

Once the loop is completed then "min" has the minimum element and "max" has the maximum element.

 

Program:

#include<stdio.h>

void main()

{

int n,i,min,max,a[50];

 

printf("How many elements?");

scanf("%d",&n);

printf("Enter %d elements:\n",n);

for(i=0;i<n;i++)

  scanf("%d",&a[i]);

for(min=max=a[0],i=1;i<n;i++)

{

      if(a[i]<min)

     min=a[i];

   if(a[i]>max)

     max=a[i];

}  

printf("Minimum element %d\nMaximum element %d",min,max);

 

}

 

Execution:

How many elements? 5

Enter 5 elements:

12   67   6   35   98

Minimum element 6

Maximum element 98

 

 Specification6:

Accept "n" elements into an array copy the element onto another array and print the resultant array.

 

Note: An array cannot be directly copied on to another array using assigning operator like normal variable.

We need to copy element by element using a loop.

Program:

#include<stdio.h>

void main()

{

int n,i,a[50],b[50];

 

printf("How many elements?");

scanf("%d",&n);

printf("Enter %d elements:\n",n);

for(i=0;i<n;i++)

   scanf("%d",&a[i]);

for(i=0;i<n;i++)

    b[i]=a[i];

printf("Resultant array elements are:\n");

for(i=0;i<n;i++)

   printf("%5d",b[i]);

 

}

 

Execution:

How many elements? 5

Enter 5 elements:

12   67   6   35   98

Resultant array elements are:

12   67   6   35   98
