Enter the string: code
All substrings of string 'code' are:
code ode de cod co c o d e

Implementation:

#include <stdio.h> #include <string.h> #include <stdlib.h> int main(void) { char *s,temp; int i,len; s=(char*)malloc(sizeof(char)); printf("Enter the string:\n"); scanf("%s",s); printf("All substrings of string '%s' are:\n"); i=0; len=strlen(s)-1; for(i=0;i<len;i++) { printf("%s ",(s+i)); } while(len>1) { temp=*(s+len); *(s+len)='\0'; printf("%s ",s); *(s+len)=temp; len--; } i=0; while(*(s+i)) { printf("%c ",*(s+i)); i++; } return 0; }
