I have solve the problem in C code with comments for easy understanding :)

CODE-

//c code

int main(void)
{
//Local variables
int ch, line,upper,punct,lower;
//Assigning values to variables
line=0;
upper=0;
punct=0;
lower=0;

//check the condition using for loop
for(ch=getchar(); ch!=EOF; ch=getchar())
{
putchar(ch);
//check the condition whether it encountered a
//new line
if(ch =='\n')
++line;
//check the condition whether it encountered a
//punctuation
else if(ispunct(ch))
++punct;
//check the condition whether it encountered a
//lower case letter
else if(islower(ch))
++lower;
//check the condition whether it encountered a
//upper case letter
else if(isupper(ch))
++upper;
}

//Printing the result
printf("\n The %d lines of text processed ",line);
printf("contained %d capital letters,",upper);
printf("%d lowercase letters,\n",lower);
printf("and %d punctuation marks\n",punct);
//return successfully
return 0;

}
