Function to Check if string input from user is alphabetic only
Good Evening. I'm new to C. Can you please help me.
I'm creating an error checking function, user will input a string, this will check if the input is all alphabet or all letters only. If there is a digit or other special char, it will print Error then ask input from user again.
Here's my code. I don't know what's wrong
int isValid (const char str[], const int max) {
int i;
for (i=0; i<= max; i++) {
if (isdigit(str[i])) {
printf("Letters and spaces are only allowed\n");
return 1;
}
else {
return 0;
}
}
}
I'm from the Philippines. Thank you very much.

How to check the user input to be valid using shell script?
The valid input is in the format like as follows.
1. It can only have r,w,x or a hyphen and nothing else.
2. ensure the r, w, x are in the correct order.
for example: rwxr-xr-x is a valid format.

plstring3
PLSTRING3(3plplot) PLplot API PLSTRING3(3plplot)
NAME
plstring3 - Plot a glyph at the specified 3D points
SYNOPSIS
plstring3(n, x, y, z, string)
DESCRIPTION
Plot a glyph at the specified 3D points. (Supersedes plpoin3(3plplot) because many[!] more glyphs are accessible with plstring3(3plplot).)
Set up the call to this function similar to what is done for plline3(3plplot). The glyph is specified with a PLplot user string. Note that
the user string is not actually limited to one glyph so it is possible (but not normally useful) to plot more than one glyph at the speci-
fied points with this function. As with plmtex(3plplot) and plptex(3plplot), the user string can contain FCI escapes to determine the
font, UTF-8 code to determine the glyph or else PLplot escapes for Hershey or unicode text to determine the glyph.
Redacted form: plstring3(x, y, z, string)
This function is used in example 18.
ARGUMENTS
n (PLINT, input)
Number of points in the x, y, and z arrays.
x (PLFLT *, input)
Pointer to an array with X coordinates of points.
y (PLFLT *, input)
Pointer to an array with Y coordinates of points.
z (PLFLT *, input)
Pointer to an array with Z coordinates of points.
string (const char *, input)
PLplot user string corresponding to the glyph to be plotted at each of the n points.
