Nptel Week 11 Programming Assignment Answers:

Q.1: The velocity of a car at different time instant is given as

      

Code:

int i,j; float x,y,k=0; for(i=0;i<5;i++){ x=1; y=1; for(j=0;j<5;j++){ if(j!=i){ x=x*(a-t[j]); y=y*(t[i]-t[j]); } } k=k+((x/y)*v[i]); }

Q.2: Write a C program to find integration of x^2dx with limit a to b using Trapezoidal rule with 10 segments between a and b.

Code:

int i; float h,x,summ=0; if(b>a){ h=(b-a)/n; } else{ h=-(b-a)/n; } for(i=1;i<n;i++){ x=a+i*h; summ=summ+func(x); } integral=(h/2)*(func(a)+func(b)+2*summ); printf("The integral is: %0.6f\n",integral); return 0; } float func(float x) { return x*x; }

Q.3: Write a C program to check whether the given input number is Prime or not using recursion.

Code:

int checkPrime(int num, int i){ if(i==1){ return 1; } else{ if(num%i==0){ return 0; } else{ return checkPrime(num,i-1); } } }

Q.4: Write a C program to reverse a word using Recursion. Input to the program is a string that is to be taken from the user and output is reverse of the input word. Note that you have to use recursion.

Code:

char* reverse(char strr[]) { static int i= 0; static char rever[MAX]; if (*strr) { reverse(strr+1); rever[i++]= *strr; } return rever; }
