Reading a file into array

Hi,

I need to read a file into array and print them in a loop:-
1st file :-cat a.txt
RC1
RC2
RC3
RC4

My Program:-
Code:
#!/bin/ksh
index=0
while [ $index -lt 5 ]
do
       read cnt[index]<a.txt
       print "cnt [$index] value is ${cnt[index]}
       index=`expr $index + 1`
done

Moderator's Comments:
Mod Comment Code tags for code, please.

Result expected :-
Code:
cnt[0] value is RC1
cnt[1] value is RC2
cnt[2] value is RC3
cnt[3] value is RC4

But i am getting the below result :-
Code:
cnt[0] value is RC1
cnt[1] value is RC1
cnt[2] value is RC1
cnt[3] value is RC1

I think there is a problem the way i am reading the file into the array

NAME
glEnableVertexAttribArray, glDisableVertexAttribArray - Enable or disable a generic vertex attribute array C SPECIFICATION
void glEnableVertexAttribArray(GLuint index); void glDisableVertexAttribArray(GLuint index); PARAMETERS
index Specifies the index of the generic vertex attribute to be enabled or disabled. DESCRIPTION
glEnableVertexAttribArray enables the generic vertex attribute array specified by index. glDisableVertexAttribArray disables the generic vertex attribute array specified by index. By default, all client-side capabilities are disabled, including all generic vertex attribute arrays. If enabled, the values in the generic vertex attribute array will be accessed and used for rendering when calls are made to vertex array commands such as glDrawArrays(), glDrawElements(), glDrawRangeElements(), glMultiDrawElements(), or glMultiDrawArrays(). ERRORS
GL_INVALID_VALUE is generated if index is greater than or equal to GL_MAX_VERTEX_ATTRIBS. ASSOCIATED GETS
glGet() with argument GL_MAX_VERTEX_ATTRIBS glGetVertexAttrib() with arguments index and GL_VERTEX_ATTRIB_ARRAY_ENABLED glGetVertexAttribPointerv() with arguments index and GL_VERTEX_ATTRIB_ARRAY_POINTER SEE ALSO
