THE PAIN OF HARD Work OR THE PAIN OF REGRET? I am President CASE and I want to organize different events at CASE.     You are Programmers.  I am not Interested in organizing event just for one time.  But next time I don't want to spend time on events on which I have already Spend a lot of time.  Give Suggestions so that with passage of time things become simple and manageable.  Do u remember story of ◦ LAKARHARA n us k Betay  Yes divide your problems into small problems and it becomes easy to solve small problems                                                                                     Indoor Activities  outdoor Activities  Sports  Trips outDoor Find Factorial of a number void main() { int r,c,f,n; n=5; f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); } void main() { int r,c,f,n; n=5; f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); } Lets Separate the Factorial code using { and } void main() { int r,c,f,n; n=5; { f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); } } void main() { int r,c,f,n; n=5; factorial() { f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); } } Lets put the factorial code separate from main Function factorial() { f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); } What is the value of n??? factorial() { n=5; f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); } Means this is a Fixed Code???  Int factorial(int n) { int c,f; f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); return f; } Void main() { int n,fn; scanf(“%d”,&n); fn=factorail(n); printf(“factorial of %d =%d”,n,fn); }  Cricket Team Example 2  Find if a number is even or odd  Find factorial of a number  Find sum of numbers  Print table of a number  Void main()  {  } void main() { int n; for(a=1;a<=100;a=a+1) { } } Int factorial(int n) { int c,f; f=1; for(c=1;c<=n;c=c+1) { f=f*c; } printf(“%d”,f); return f; } Table of a Number void table(int n) { int c,t; for(c=1;c<=10;c=c+1) { t=n*c; printf(“\n%d*%d= %d”,n,c,t); } } void main() { int a,b,n,fn; for(a=1;a<=100;a=a+1) { b=a%2; if(b==0) { //a is even } else { //a is odd } } } Even Odd void main() {int a,b,n,fn; for(a=1;a<=100;a=a+1) { b=a%2; if(b==0) { f=1; for(c=1;c<=a;c=c+1) { f=f*c; } printf(“%d”,f); } else { //a is odd } } } Factorial of Even Number void main() {int a,b,n,fn; for(a=1;a<=100;a=a+1) { b=a%2; if(b==0) { } else { for(c=1;c<=10;c=c+1) { t=a*c; printf(“\n%d*%d=%d”,a,c,t); } } } } Table of Odd Numbers Which code is Easy to read write Understand Debug change ????????????????????????  So Functions are to MAKE YOUR LIFE EASY.  Zindagi Assan ho jati ha Functions sa      You are forgetting one thing void main() {int a,b,n,fn; for(a=1;a<=100;a=a+1) { b=a%2; if(b==0) { f=1; for(c=1;c<=a;c=c+1) { f=f*c; } Sum=sum+fn; printf(“%d”,sum); } else {  for(c=1;c<=10;c=c+1) { t=n*c; printf(“\n%d*%d=%d”,n,c,t);  } } } } Even Odd void main() { int a,b,n,fn; for(a=1;a<=100;a=a+1) { b=a%2; if(b==0) { fn=factorial(a); sum=sum+fn; } else { Table(a); } } }  Find sum of series 1!+2!+3!+4!+5! void main() { int a,b,n,fn,sum; sum=0; for(a=2;a<=6;a=a+1) { fn=factorial(a); sum=sum+fn; } printf(“%d”,sum); }  Find sum of series 1!+3!+5!+7!+9! void main() { int a,b,n,fn,sum; sum=0; for(a=1;a<=10;a=a+2) { fn=factorial(a); sum=sum+fn; } printf(“%d”,sum); }  Find sum of series 1 /1!+ 1 / 2!+ 1 / 3!+ 1 /4!+ 1 / 5! void main() { int a,b,n,fn,sum; sum=0; for(a=1;a<=5;a=a+1) { fn=factorial(a); sum=sum+1/fn; } printf(“%d”,sum); }  Find sum of series  2 /1!+ 2 / 2!+ 2 / 3!+ 2 /4!+ 2 / 5! void main() { int a,b,n,fn,sum; sum=0; for(a=1;a<=5;a=a+1) { fn=factorial(a); sum=sum+a/fn; } printf(“%d”,sum); }  Find sum of series 1 /2!+ 2 / 4!+ 3 / 6!+ 4 /8!+ 5 / 10! void main() { int a,b,n,fn,sum; sum=0; for(a=1;a<=5;a=a+1) { b=2*a; fn=factorial(b); sum=sum+a/fn; } printf(“%d”,sum); } void main() { int a,b,n,fn,sum; sum=0; for(a=1;a<=5;a=a+1) { b=2*a; C=a*10; fn=factorial(b); sum=sum+c/fn; } printf(“%d”,sum); } void main() { int a,b,n,fn,sum; sum=0; b=2; c=10; for(a=1;a<=5;a=a+1) { fn=factorial(b); sum=sum+c/fn; b=b+2; c=c+10; } printf(“%d”,sum); }  Int sq(int n)  {  int c;  c=n*n;  return c;  } int power(int b,int p) { int c; int f=1; for(c=1;c<=5;c++) { f=f*2; } return c; } int power(int b,int p) { int c; int f=1; for(c=1;c<=p;c++) { f=f*2; } return c; } int power(int b,int p) { int c; int f=1; for(c=1;c<=p;c++) { f=f*b; } return c; } int read1darray(int *arr,int n) { int c; for(c=0;c<n;c++) { scanf(“%d”,&arr[a]); } } int print1darray(int *arr,int n) { int c; for(c=0;c<n;c++) { printf(“%d”,arr[a]); } } int read2darray(int arr[][5],int nr) { int r,c; for(r=0;r<nr;r++) { for(c=0;c<nr;c++) { scanf(“%d”,&arr[r][c]); } } }
