1 #include <stdio.h> 2 #include <string.h> 3 int distance(char str1[]) 4 { 5 int len; 6 len=strlen(str1); 7 return len; 8 } 9 int main() 10 { 11 char str[2][10]; // if str[2][7] 12 int i; 13 for(i=0;i<2;i++) 14 scanf("%s", str[i]); 15 int len1, len2; 16 len1 = distance(str[0]); 17 len2 = distance(str[1]); 18 printf("%d, %d\n", len1, len2); 19 return 0; 20 }
intput:
abcdefg
abcdefg
output:
7, 7
//if str[2][7]
input:
abcdefg
abcdefg
output:
14, 7
comment: there is a need for one position for '\0' in str[2][7] since strlen count number stopping by '\0'!
