write a C program that a number with a decimal point is the sum of two parts : an integer part before the decimal point and a fractional part which is after the decimal point. For example, 2.43 has 2 as the integer part and .43 as the fractional part. Similarly, -3.546 has -3 as the integer part and -.546 as the fractional part. write a program that asks you to input a number of the type double, and then outputs its integer part. for example if the input is 2.43, the output should be 2. if the input is -3.546, the output should be -3.
