**Write a C program to find the greatest of three numbers.**

**Program:**

#include
<stdio.h>

int main()

{

int a, b, c;

printf("Enter
a,b,c: \n");

scanf("%d %d
%d", &a, &b, &c);

if (a > b &&
a > c)

{

printf("a is
Greater than b and c");

}

else if (b > a
&& b > c)

{

printf("b is
Greater than a and c");

}

else if (c > a
&& c > b)

{

printf("c is
Greater than a and b");

}

else

{

printf("all are
equal or any two values are equal");

}

return 0;

}

**Output:**

Enter a,b,c: 3 5 8

c is Greater than a
and b

**Explanation with examples:**

Consider three
numbers a=5,b=4,c=8

if(a>b &&
a>c) then a is greater than b and c

now check this
condition for the three numbers 5,4,8 i.e.

if(5>4 &&
5>8) /* 5>4 is true but 5>8 fails */

so the control shifts
to else if condition

else if(b>a
&& b>c) then b is greater than a and c

now checking this
condition for 5,4,8 i.e.

else if(4>5
&& 4>8) /* both the conditions fail */

now the control
shifts to the next else if condition

else if(c>a
&& c>b) then c is greater than a and b

now checking this
condition for 5,4,8 i.e.

else if(8>5
&& 8>4) /* both conditions are satisfied */

Thus c is greater
than a and b.
