hi @shubhangis248 please share your code using ide.codingblocks.com

hi @shubhangis248 you are forming a character array, either form an array of strings or a 2D character array to store all the strings. Or if you want to use only a single array then you will have to run a loop n times to do so

#6
#7

did the same as what you told but still getting error

#8

hi @shubhangis248 modify line 36
it should be pireplace(a[i],0);
because you are sending only 1 string at a time.

@shubhangis248 corrected code https://ide.codingblocks.com/s/335474
