{
if ( c>=b )
b += a;
a += b;
}
printf(“a=%d\n", a);
printf(“b=%d\n", b);
}
(c) what will be output after executing following part :
main ( )
{
int i = 100, sumx = 100;
for ( ; i<=200 ; i+<2)
{
Sumx = sumx + i;
printf(“ sumx=%d\n", sumx);
printf(“i=%d", i );
}
}
(d) What will be the output ?
main( )
{
int a=10, b=20;
clrscr( );
printf(“a=%d\n b=%d\n", a, b);
sweep (a, b);
printf(“a=%d\n b=%d\n", a, b);
}
sweep (int a, int b)
{
int t;
t=a;
a=b;
b=t;
return;
}
(e) Find and display output
main( )
{
float a=3.230719;
printf(“\n %6.2 f", a);
printf(“\n %5.4 f", a);
printf(“\n %2.1 f", a);
printf(“\n %0.0 f", a);
}
3 (a) Write a ‘C' program for finding sum as those nos between n1 5
and n2 which can be divisible by n3 with reminder zero. Accept n1,n2 and n3 from terminal.
OR
(a) Write ‘C' program for finding the sum of following : 5
2
1+ 3
accept n from terminal.
(b) Write a ‘C' prog. Which will write the first 25 fibonacci
nos. into? one file. Display these nos on terminal.
OR
(b) (1) Write a ‘C' prog. which display the accepted string 5
in reverse order without using any build-in library
string functions.
(2) Write a ‘C' prog. for sweeping two nos. without 5
using third variable.
(c) Write a ‘C' prog. for addition of 3*3 matrix. Display 2
Ans matrix.
4 (a) Write short notes on any three : 6
1. Circle( ), Ellipse( ), getx( ), gety( ).
2. Switch statement
3. Basic structure of ‘C' lang.
4. Advantages of pointer.
(b) State true or false with reason. 1
In the ‘C' prog. language every line of statement must be
ended by semicolon.
(c) What will be the value of b? 1
int x = 100, b = 0;
b = (x>=100) ? x/2 : x/3;
(d) Find and show syntax errors (if any) 2
main( )
{
int x = 100; y = 20; a = 100;
cls( )
printf(“%d %d", x);
y = getchar( );
while (x = 100)
x + +;
y + = a;
