}
int fact(int x)
{
int fac=1,i;

41] Program to show table of a number using functions.
#include<stdio.h>
#include<conio.h>
void main()
{
void table();
clrscr();
table();
getch();
}


void table()
{
int n,i,r;
printf(“enter a no to know table: ”);
scanf(“%d”,&n);
for(i=1;i<=10;i++)
{
r=n*i;
printf(“%d*%d=%d\n”,n,i,r);
}
}

 Output:
enter a no to know table: 2
2*1=2
2*2=4
2*3=6
2*4=8
2*5=10
2*6=12
2*7=14
2*8=16
2*9=18
2*10=20
42] Program to show call by value.
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,swap();
clrscr();
a=5;
b=10;
printf(”value of a=%d & value of b=%d before swap ”,a,b);

printf(“\nvalue of a =%d & b=%d after swap”,a,b);
getch();
}
int swap(int x,int y)
{
int temp;
temp=x;
x=y;
y=temp;
}

 Output:
value of a=5 & value of b=10 before swap
value of a=5 & b=10 after swap

43] Program to show call by reference.
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,*aa,*bb,swap();
clrscr();
a=5;
b=10;
aa=&a;
bb=&b;
printf(“value of a= %d & value of b=%d before swap”,a,b);
swap(aa,bb);
printf(“\nvalue of a=%d & b=%d after swap”,a,b);
getch();
}
int swap(int *x,int *y)
{
int temp;
temp=*x;

*x=*y;
*y=temp;
}
 Output:
value of a= 5 & value of b=10 before swap
value of a=10 & b=5 after swap

44] Program to find largest of two numbers using functions.
#include<stdio.h>
#include<conio.h>
void main()
{
void max();
clrscr();
max();
getch();
}
void max()
{
int a[5],max,n,i;
printf(“How many no’s you want to enter: ”);
scanf(“%d”,&n);
printf(“Enter element for the array: ”);
for(i=0;i<n;i++)
scanf(“%d”,&a[i]);
max=a[0];
for(i=1;i<5;i++)
{
if(max<a[i])
max=a[i];
}
printf(“maximum no= %d”,max);
}

Output:
How many no’s you want to enter: 4
Enter element for array: 4
5
6
1
maximum no: 6
45] Program to find factorial of a number using recursion.
#include<stdio.h>
#include<conio.h>
void main()
{
int n;
clrscr();
printf(“enter number: ”);
scanf(“%d”,&n);
if(n<0)
printf(“invalid number”);
else
printf(“%d!=%d”,n,fact(n));
getch();
}
int fact(int x)
{
if(x==0)
return 1;
else
return(x*fact(x-1));
}
 Output:
enter number: 5
5!=120
46] Program to find whether a string is palindrome or not.
#include<stdio.h>
#include<conio.h>
#include<string.h>

void main()
{
char s1[20],s2[20];
clrscr();
printf(“enter a string: ”);
scanf(“%s”,s1);
strcpy(s2,s1);
strrev(s2);
if(strcmp(s1,s2)==0)
printf(“string is a palindrome”);
else
printf(“not a palindrome string”);
getch();
}
 Output:
enter a string: abc
not a palindrome string
