Some string functions


in c i will implement.
Main job of this function is to print a new line autoamtically where printf() does not give this.



The actual work of putchar is it display string as character by character putchar is a macro that outputs character on stdout.

and the basic is : putchar(‘a’)    // it will print a
and putchar(a);     //it will print the value in stored in a
And the basic parameters of this is:
int putchar(int c);

Take input in string:

In string we don’t mention ampersand & sign as string automatically take it as address.


String equality:

String Lower:

String Upper:

Here we have to think like a child :D….So first we took a character array where we will take input string.And if the input is = 5 then it will print three as per the input set.And then when we enter the value input like ‘t’ and ‘o’ and ‘w’ then we can make it out from the string.So we have added this like this if t and w or if t or o or w or o is available then we will print 2 in the output where in string array t in the position 1, w is in the position 2, o is in the position 3

So basically the output case 2 we made the condition in the logic.

Note: In logic we must have to follow the sequence of the text One,Two,Three as suppose in two it can be two,too,ooo,owo  and as the input will do at most 100 words.So this steps has been taken 🙂
