This is the program which makes use of function matchany(s1,s2) which returns the first location in the string s1 where any character from the string s2 occurs, or -1 if s1 contains no character from s2.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | #include "stdio.h" #include "conio.h" #include "string.h" void main() { int matchany(char str1[],char str2[]);//function declaration char str1[50],str2[50]; int s; clrscr(); printf("Enter string 1 and string 2\n"); scanf("%s%s",&str1,&str2); s=matchany(str1,str2); if(s==-1) printf("\nNo match found"); else printf("\nThe location where the first match occured is %d",s); getch(); } int matchany(char str1[],char str2[]) { int i,j; for(i=0;i<strlen(str2);i++) { for(j=0;j<strlen(str1);j++) { if(str2[i]==str1[j]) { return j+1; } } } return -1; } |
output 1:
Enter string 1 and string 2 hello world The location where the first match occured is 5 |
Output 2:
Enter string 1 and string 2 ice smooth No match found |
