strdel (3pub)

#include <publib.h>
char *strdel(char *s, size_t n);

strdel removes the first n characters of s. If n is greater than the length of the string, all characters in the string (not counting '\0') are removed but no more.

strdel returns its first argument.

To change all occurences of "Pascal" in the input to "Yuck!", you might do the following:

#include <string.h>
#include <stdio.h>
#include <publib.h>

int main(void) {
	char line[512];

	while (fgets(line, sizeof(line), stdio) != NULL) {
		while ((p = strstr(line, "Pascal")) != NULL) {
			strdel(p, 6);
			strins(p, "Yuck!");
		}
		printf("%s", line);
	}
	return 0;
}
