Final answer:
The correct expressions to find the minimum value in a two-dimensional array are 'userVals[i][j]' for XXX and 'minVal = userVals[i][j]' for YYY, using a nested for loop to iterate over the elements.
Step-by-step explanation:
The question is asking for the correct expressions to find the minimum value of all the elements in a two-dimensional array in C/C++ programming. To find the minimum value in the array, you need to compare each element with the current minimum value and update the minimum value if a smaller element is found. The correct expressions to use are userVals[i][j] for XXX and minVal = userVals[i][j] for YYY. Here is the completed loop:
int minVal = userVals[0][0];
for (int i = 0; i < NUM_ROWS; ++i) {
for (int j = 0; j < NUM_COLS; ++j) {
if (userVals[i][j] < minVal) {
minVal = userVals[i][j];
}
}
}
This nested for loop iterates through all elements in the array and updates minVal whenever it finds an element smaller than the current minimum.
