Language C

1. Please save the program with the name ‘triangle.c’
Write a nested for loop that prints the following output:
1
1 2 1
1 2 4 2 1
1 2 4 8 4 2 1
1 2 4 8 16 8 4 2 1
1 2 4 8 16 32 16 8 4 2 1
1 2 4 8 16 32 64 32 16 8 4 2 1
1 2 4 8 16 32 64 128 64 32 16 8 4 2 1
Hint: Here is the psudocode solution:
for row from 0 to 7 {
pad leading blanks in a row like this
for the column from 1 to 7-row:
print a set of spaces
print left half of row
for column from 0 to row:
print spaces followed by 2 raised to the power of the column
print right half of row
for column from row-1 to 0:
print spaces followed by 2 raised to the power of the column
print a new line
You need to figure out how many spaces to print before the number. The simple way to
compute powers of 2 is with the pow function; can you do this without it?

2. Please save the program with the name ‘grade.c’
Write a program that will prompt the user to input ten student scores to an array. The score
value is between 0 – 100. The program will display the smallest and greatest of those values. It
also displays the average score.
Example:

please input student scores one at a time. Student 1: -10 Try again! Student 1:10 Student 2110 Try again! Student 220 3:30 Student 4 : 4? 5 50 Student 6: 60 Student 7: 70 Student 8:80 Student 990 Student Student Student 10 : 1?? The maximum score is 100 The minimum score is 10 The averange score is 55

Explanation / Answer

Hello there!!!

I have wrote working codes for both problems

###########################################################

[1]

#include<stdio.h>

int power(int b,int d) {

if(d==0)

return 1;

else

return b*(power(b,d-1));

}

int main()
{
    int i,j,k;

    for(i=0;i<8;i++)
    {
        for (j=0;j<i;j++)
        {
k = power(2,j);
            printf("%d ",k);
        }
        for(j=i;j>=0;j--)
        {
k = power(2,j);
            printf("%d ",k);
        }
        printf(" ");
    
    }
    return 0;
}

#include<stdio.h>
#include<limits.h>

int main(){
  
int scores[10];
int min=100,max=0,sum=0;
float avg;
fprintf(stdout,"Please input student scores one at a time. ");
  
for(int i=0;i<10;i++) {
again:
fprintf(stdout,"Student %d : ",(i+1));
fscanf(stdin,"%d",&scores[i]);
  
if(scores[i]<0 || scores[i]>100) {
fprintf(stdout,"Try again! ");
goto again;
}

if(scores[i]>max)
max=scores[i];
if(scores[i]<min)
min=scores[i];
  
sum+=scores[i];
}
fprintf(stdout,"*****************Final Result**************** ");
fprintf(stdout,"The maximum score is %d ",max);
fprintf(stdout,"The minimum score is %d ",min);
fprintf(stdout,"The average score is %f ",(float)(sum/10));
  
return 0;
}
