The following is the output of this program:

 The first month of year is January.

 The seventh month, July, is named after Julius Caesar.

 Our calendar has 12 months.

 January is made of 7 letters:  J a n u a r y
 February is made of 8 letters:  F e b r u a r y
 March is made of 5 letters:  M a r c h
 April is made of 5 letters:  A p r i l


The following array could be used if you improve this program:

      char*  history_of_months[] =
      {  "month of Roman god Janus",      // January
         "last month in Roman calendar",  // February
         "month of Roman war god Mars",   // March
         "month of Roman goddess Venus",  // April
         "month of goddess Maia",         // May
         "month of Roman goddess Juno",   // June
         "month of Julius Caesar",        // July
         "month of Emperor Augustus",     // August
         "7th Roman month",               // September
         "8th Roman month",               // October
         "9th Roman month",               // November
         "10th Roman month"  } ;          // December
