int i, n = 20;
for (i = 0; i < n; i--)
printf("-");

You have to print '-' 20 times. by adding or removing or replacing only
a single character from the code.
There are 3 possible solutions for the above question. Can u get them?

here goes:
1. replace i with n in the for() loop
2. make it -i < n
3. in for() loop init i as 40 (for(i=40;i < 20 ... )

so there :-)

hi all,

here are the 3 solutions, in case you still want to give it a try.. dont look at the solutions below:

CODE

int i, n = 20;
for (i = 0; i < n; n--)
printf("-");

CODE

int i, n = 20;
for (i = 0; -i < n; i--)
printf("-");

CODE

int i, n = 20;
for (i = 0; i + n; i--)
printf("-");
