It does not return an error .
the output would be
x=9, y=9x=9, count of earlier print=8

HINT: try and understand the way printf evaluation works (right to left or left to right), also keep in mind when printf is called and what argument values are passed and when exactly is the data written to STDOUT

Answer / aditya lele

By the way the error that you are talking about is because
of the fact that your function has an integer return type
and you are not returning anything.
add a

return 0;

at the end before you close the main()

int i=10; main() { extern int i; { int i=20; { const volatile unsigned i=30; printf("%d",i); } printf("%d",i); } printf("%d",i); }

Write a C program that defines a 2-dimentional integer array called A [50][50]. Then the elements of this array should randomly be initialized either to 1 or 0. The program should then print out all the elements in the diagonal (i.e. a[0][0], a[1][1],a[2][2], a[3][3], ……..a[49][49]). Finally, print out how many zeros and ones in the diagonal.
