Programme C : Remplacer un mot dans un texte par un autre mot donné

text = “I am learning programming” oldword = “learning” newword = “practicing”

“I am practicing programming”

#include  #include  #include  void replaceWordInText(const char *text, const char *oldWord, const char *newWord) { int i = 0, cnt = 0; int len1 = strlen(newWord); int len2 = strlen(oldWord); for (i = 0; text[i] != '\0'; i++) { if (strstr(&text[i], oldWord) == &text[i]) { cnt++; i += len2 - 1; } } char *newString = (char *)malloc(i + cnt * (len1 - len2) + 1); i = 0; while (*text) { if (strstr(text, oldWord) == text) { strcpy(&newString[i], newWord); i += len1; text += len2; } else newString[i++] = *text++; } printf("New String: %s
", newString); } int main() { char str[] = "I am learning programming"; char c[] = "learning"; char d[] = "practicing"; char *result = NULL; printf("Original string: %s
", str); replaceWordInText(str, c, d); return 0; }

Original string: I am learning programming New String: I am practicing programming
