A C program to find the sum of series of polynomial #include<stdio.h> #include<math.h> void main() { int i,n,sum,a[20]; float x; printf(" enter the number of coefficients \n"); scanf("%d",&n); printf("enter the coefficients\n"); for("i=0;i<n;i++) { scanf("%d",&a[i]); } printf("enter the value for x\n"); scanf("%f",&x); sum=0; for(i=n-1;i>0;i--) { sum=sum+a[i]*pow(x,i); } printf("result is %d\n",sum); getch(); clrscr(); }

ALGORITHM Step 1: Start Step 2: [input] read n numbers Step 3: [for loop statement] Step 4:  for(i=1;i<n;i++) [loop for passing number] Step 5: for(j=0;j=n-i;j++) [loop for comparison] Step 6: [using if condition]              if(a[j]>a[j+1]) Step 7: [body of if condition]                { Step 8: temp=a[j];              a[j]=a[j+1];              a[j+1]=temp;               }               [end of if condition]               [end of step 5 j loop]               [end of step 4 i loop] Step 9: print the sorted numbers Step 10: Stop [end of the algorithm]

*)A Character is a single character enclosed within single quote like 'a','e' But a string is a set of character  stored in consecutive locations in memory and terminated by null character. For example "harish" *)A character constants has an equivalent integer value. A string character string constant does not have an equivalent integer value

When Volkswagen invited its customers to think up some ideas, it was perhaps inevitable that there would be at least one flying car design put forward. But one concept – the ‘Hover Car’ – impressed the firm so much a short CGI YouTube video was made to showcase it. The video bellow shows a VW flying two-seater zipping through Beijing. The car, powered by minerals underground, was the brainchild of a girl in China who responded to the carmaker’s call for car innovation concepts. The idea is that thrusters on the back of the car would propel it forward. Getting the “car” to work for real would require electromagnetic strips embedded into the roads below it, creating the hovering effect via electromagnetic suspension. As a prize, the girl’s parents got to “test drive” the car in a simulated video. According to  Creativity Online , VW received 119,000 ideas and got 33 million hits on its website.
