int var2 = 'q';
int var3 = '3';
if( islower(var1) ) {
printf("var1 = |%c| is lowercase character\n", var1 );
} else {
printf("var1 = |%c| is not lowercase character\n", var1 );
}
if( islower(var2) ) {
printf("var2 = |%c| is lowercase character\n", var2 );
} else {
printf("var2 = |%c| is not lowercase character\n", var2 );
}
if( islower(var3) ) {
printf("var3 = |%c| is lowercase character\n", var3 );
} else {
printf("var3 = |%c| is not lowercase character\n", var3 );
}
return(0);
