Write a program in c to find the factorial of a number #include <stdio.h> int main(){   int i=1,f=1,num;   printf( "Enter a number: " );   scanf( "%d" ,&num);   while (i<=num){       f=f*i;       i++;   }   printf( "Factorial of %d is: %d" ,num,f);   return 0; } Sample output: Enter a number: 5 Factorial of 5 is: 120 Do you know what is zero (0) Factorial ?

visit the problem source :  #include <stdio.h> #include<conio.h> int main () { int n,i,s,p,j; clrscr(); printf("Enter your range(n) :"); scanf("%d",&n); p=1; for (i=1;i<=n;i++) { s=0; for (j=1;j<=i;j++) { s=s+i; } p*=s; } printf("\n The value of p is =%d",p); getch(); return 0; } sample input/output: input : 4 output : The value of p is =576

This prints out all acsii values void main () { int i ; i = 0 ; do { printf ( "%d %c \n" , i , i ); i ++; } while ( i <= 255 ); } This prints out the acsii value for a given character:   void main () { int e ; char ch ; clrscr (); printf ( "\n Enter a character : " ); scanf ( "%c" , ch ); e = ch ; printf ( "\n The ASCII value of the character is : %d" , e ); getch (); }

#include <stdio.h> #include <conio.h> int  main () {    int  n =  0 ;    loop: ;      printf ( "\n%d" , n ) ;    n++;    if  ( n< 10 ) {    goto  loop;    }    getch () ;    return  0 ; }

#include <stdio.h> #include<conio.h> int main() { int i; float fArray[4]; clrscr(); for (i = 0; i < 4; i++) { printf("Please enter a float: "); scanf("%f", fArray[i]); } getch(); return 0; } output:
