Question

C programming

3. Write a do-while loop that displays: 0,10,20,30,40

4.Write nested for loops that displays three rows of asterisks:

*****

*****

*****

5. Write a complete program that reads a set of integers using scant() until a sentinel value of -99 is read. Once that value is read, display the sum of the value read, exclusive of the -99.

6.Write a procedure(function, method named times10() that accepts an integer argument and displays the result of multiplying the argument by 10.

7.Write a function prototype for a min3() function that accepts three integer parameters and returns an integer value.

8.Write the function implementation for the min3() function. Return the minimum value of the three.

3.

#include <stdio.h>

int main(void) {
  
   int x = 0;
   do
   {
   printf("%d",x);
   if(x < 40)
   printf(",");
   x = x+ 10;
   }while(x<= 40);
  
   return 0;
}

Output:

0,10,20,30,40

4.

#include <stdio.h>

int main(void) {
  
   int i,j;
   for(i=1;i<=3;i++)
   {
       for(j=1;j<=5;j++)
       {
           printf("*");
       }
       printf("\n");
   }
  
   return 0;
}

Output:

*****
*****

#include <stdio.h>

int main(void) {
  
   int x, sum;
   sum = 0;
  
   do
   {
      
   scanf("%d",&x);
   if(x == -99)
   break;
   sum = sum + x;
   }while(x != -99);
  
   printf("\nSum = %d",sum);
   return 0;
}

Output:

8 -5 7 6 -99

Sum = 16

6.

#include <stdio.h>

int times10(int x)
{
   return 10*x;
}
int main(void) {
  
   printf("%d",times10(4));
  
   return 0;
}

Output

40

7.

int min3(int x,int y,int z);

8.

#include <stdio.h>

int min3(int x,int y,int z)
{
   if(x < y)
   {
       if(x < z)
       return x;
       else
       return z;
      
   }
   else
   {
       if(y < z)
       return y;
       else
       return z;
   }
}
int main(void) {
  
   printf("%d",min3(54,66,12));
  
   return 0;
}

Output:

12
