Answer / manish
post= a++ * a++ * a++;
a++ is post increment so 3*3*3=27 and then a is incremented
pre= ++a * ++a * ++a;
++a pre increment
consider ++a * ++a
a incremented two times first result is 5 => 5*5=25
now we have 25 * ++a (a is 5)
a is again incremented (a become 6)
25 * 6 =150 ans

Is the following code legal? struct a { int x; struct a *b; }
main() { int i, j, *p; i = 25; j = 100; p = &i; // Address of i is assigned to pointer p printf("%f", i/(*p) ); // i is divided by pointer p } a. Runtime error. b. 1.00000 c. Compile error d. 0.00000
what will be the output of this program? void main() { int a[]={5,10,15}; int i=0,num; num=a[++i] + ++i +(++i); printf("%d",num); }
How do you write a program which produces its own source code as its output?
main() { int i; float *pf; pf = (float *)&i; *pf = 100.00; printf("\n %d", i); } a. Runtime error. b. 100 c. Some Integer not 100 d. None of the above
