I am trying to expand on a earlier program for counting subs and now i am trying to replace substrings within a given string. For example if the main string was "The cat in the hat" i am trying to find a chosen substring lets say "cat" and then replace it with a difrent inputed substring say "dog". Tried to get as far as i could on my own but need some help, sugestions, snippets or guidence.

need help! replacing substing in a string with another substring
-
Thanks for the help i have it figured out with the suggestions, below is a chunk of the code i needed to add, hope others others can learn from it.
[code=c]
char *q;//pointer
int count=0; for (i=0;i<length;i ++)
q[i]=subcap[i];
q=strstr(q+1,s2 );
q=strstr(s1,s2) ;
while (q!= NULL)
{q=strstr(q+1,s 2);
count++;}//counter
[/code] -
No help yet? can anyone tell me where the return value from the strstr goes and am i able to check to see if it is null or not by if statments? Further does the return value to the array need to be 0 or should it be a pointer to s1 or s2?...Leave a comment:
