1 .One programming language has the following keywords that cannot be used as identifiers:
break, case, continue, default, defer, else, for, func, goto, if, map, range, return, struct, type, var
Write a program to find if the given word is a keyword or not
Input #1:
defer
Output:
defer is a keyword
Input #2: While
Output: while is not a keyword

#include<string.h>

char str[16][10] = {"break", "case", "continue", "default", "defer", "else","for",

2.Given a pair of positive integers m and n (m < n; 0 < m < 999; 1 < n < = 999), write a program to smartly affix zeroes, while printing the numbers from m to n.
Example-1
Input
5 10
Expected output
05 06 07 08 09 10
Example-2
Input
9 100
Expected output
009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 067 068 069 070 071 072 073 074 075 076 077 078 079 080 081 082 083 084 085 086 087 088 089 090 091 092 093 094 095 096 097 098 099 100
