No, 100 crunches a day won't automatically give you abs because visible abs require a low body fat percentage, achieved through diet and overall exercise, not just crunches; crunches strengthen your abdominal muscles but won't burn the fat covering them, a concept known as spot reduction, which isn't possible. You need a combination of a healthy diet (calorie deficit), full-body strength training (including weights), cardio, and core work (like crunches) to reveal your abs.
