I would like to create an integer list in C containing integer arrays of variable size. The length of the main list will not need to change.
How would I declare it - my implementation - particularly my access is not working:
int dataArray[length];
int dataArray[0] = [1,2,3];
int dataArray[1] = [5,6];
.
.
.
populate
for(int a = 0; a<sizeof(dataArray); a++) {
tempArr = dataArray[a];
for(into = 0; b>sizeof(tempArr); b++) {
print(dataArray[a][b])
}
}

Answer 1

Your main array needs to hold pointers to other arrays. Therefore it should not be int dataArray[length] but rather int* dataArray[length] this means it will hold length amount of references to integer arrays.
int* array[length];
int randomSizeArray[x];
randomSizeArray[0] = 1;
.
.
.
randomSizeArray[x] = 5;
int* array[0] = randomSizeArray;
Also sizeof() will not work the way you expect it to - in C you need to store separately how many elements are in an array. I'd recommend reading a C tutorial from the ground up as you seem to have shaky knowledge of basics.

Answer 2

The sizeof results in the byte count not element count.
Divide the array size by the element size to find the element count.
int dataArray[length];
int dataArray[0] = [1,2,3];
int dataArray[1] = [5,6];
...
// for(int a = 0; a<sizeof(dataArray); a++) {
for(size_t a = 0; a<sizeof(dataArray)/sizeof(dataArray[0]); a++) {
tempArr = dataArray[a];
// for(into = 0; b>sizeof(tempArr); b++) {
for(into = 0; b>sizeof(tempArr)/sizeof(tempArr[0]); b++) {
// or do you really want
// for(size_t = 0; b<sizeof(tempArr)/sizeof(tempArr[0]); b++) {
print(dataArray[a][b])
}
}
