Code:
#include
void swap34(float *ptr1, float *ptr2);
void main()
{
float x[10];
int i, n;
printf("How many Elements...\n");
scanf("%d", &n);
printf("Enter Elements one by one\n");
for (i = 0; i < n; i++)
{
scanf("%f", x + i);
}
/* Function call:Interchanging 3rd element by 4th */
swap34(x + 2, x + 3);
printf("\nResultant Array...\n");
for (i = 0; i < n; i++)
{
printf("X[%d] = %f\n", i, x[i]);
}
}
/* Function to swap the 3rd element with the 4th element in the array */
void swap34(float *ptr1, float *ptr2 )
{
float temp;
temp = *ptr1;
*ptr1 = *ptr2;
*ptr2 = temp;
}
Output:
How many Elements...
