This is what I want. I tried it many ways, but not successful. I want to copy 2nd array values to end of 1st array.
uint8_t *set = getCharacterPattern('A');
uint8_t *set2 = getCharacterPattern('B');
// Here I want to copy *set2 values to end of *set array
for (uint8_t i=0; i<(getCharacterSize(A)+getCharacterSize('B')); i++){
setLed(0,i,set[i]);
}
Please help me someone.
You need to allocate memory for combined array and copy both arrays into the new memory. I assume getCharacterSize function returns the number of elements in corresponding array.
// Combine arrays set and set2
int sizeA = getCharacterSize('A');
int sizeB = getCharacterSize('B');
int sizeBoth = sizeA + sizeB;
uint8_t *bothSets = malloc(sizeBoth * sizeof uint8_t);
memcpy(bothSets, set, sizeA * sizeof uint8_t);
memcpy(bothSets+sizeA, set2, sizeB * sizeof uint8_t);
// Use combined array
for (uint8_t i=0; i<sizeBoth; i++){
setLed(0, i, bothSets[i]);
}
// Release allocated memory
free(bothSets);
new and delete keywords are part of C++, not C.malloc() in a C program: stackoverflow.com/questions/605845/…
int len = getCharacterSize('A');
int len2 = getCharacterSize('B');
for (int i=0; i<len+len2; i++)
setLed(0,i,i<len ? set[i] : set2[i-len]);
