I want to define a hex character array in C, but I don't want to have to define the elements one at a time. my programme needs an hexadecimal array as input of 128 bits. for example, unsigned char temp2[32]= {0x00 ,0x11 ,0x22 ,0x33 ,0x44 ,0x55 ,0x66 ,0x77 ,0x88 ,0x99 ,0xaa ,0xbb ,0xcc ,0xdd ,0xee ,0xff}; the variable temp2 values need to be assigned dynamically.. since i have another integer array of size 32.e.g. paintext[32]={0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15} which will be converted to hexadecimal and dynamically allocated to temp2
