12-> Alogirthm and draw flowchart for finding the greatest number among any numbers.

Algorithm

START
INPUT FOUR NUMBERS A, B, C, D
IF A > B THEN
IF A > C THEN
IF A > D THEN
A IS THE GREATEST
ELSE
D IS THE GREATEST
ELSE IF B > C THEN
IF B > D THEN
B IS THE GREATEST
ELSE
D IS THE GREATEST
ELSE IF C > D THEN
C IS THE GREATEST
ELSE
D IS THE GREATEST

13-> WAP to read name of 10 employees and sort them in ascending order using pointer

#include <stdio.h>
void main()
{
int *a,i,j,tmp,n;
printf("nn Pointer : Sort an array using pointer :n");
printf("--------------------------------------------n");

printf(" Input the number of elements to store in the array : ");
scanf("%d",&n);

printf(" Input %d number of elements in the array : n",n);
for(i=0;i<n;i++)
{
printf(" element - %d : ",i+1);
scanf("%d",a+i);
}
for(i=0;i<n;i++)
{
for(j=i+1;j<n;j++)
{
if( *(a+i) > *(a+j))
{
tmp = *(a+i);
*(a+i) = *(a+j);
*(a+j) = tmp;
}
}
}
printf("n The elements in the array after sorting : n");
for(i=0;i<n;i++)
{
printf(" element - %d : %d n",i+1,*(a+i));
}
printf("n");
}

17-> Break and continue with suitable examples

Break statement

// Program to calculate the sum of numbers (10 numbers max)
// If the user enters a negative number, the loop terminates

#include <stdio.h>

int main() {
int i;
double number, sum = 0.0;

for (i = 1; i <= 10; ++i) {
printf("Enter n%d: ", i);
scanf("%lf", &number);

// if the user enters a negative number, break the loop
if (number < 0.0) {
break;
}

sum += number; // sum = sum + number;
}

printf("Sum = %.2lf", sum);

return 0;
}

Continue statement

// Program to calculate the sum of numbers (10 numbers max)
// If the user enters a negative number, it's not added to the result

#include <stdio.h>
int main() {
int i;
double number, sum = 0.0;

for (i = 1; i <= 10; ++i) {
printf("Enter a n%d: ", i);
scanf("%lf", &number);

if (number < 0.0) {
continue;
}

sum += number; // sum = sum + number;
}

printf("Sum = %.2lf", sum);

return 0;
}
