Need help in C

(a) Write a C program to read in a line of text and count the occurrence of each English alphabet. The lowercase version of a letter is considered the same as the uppercase. To make viewing easy, the frequencies should be presented using a bar chart as follows. You can assume that the input contains only spaces, lowercase letters, uppercase letters and the newline character (i.e. the Enter key). Enter a line of text: Letter ZZz Erequency 0 (b) The following program includes array operations and pointers arithmetic operations. The program prints several values. The meaning of the first two values are given in the following.*' The value or content element index 3 of the array temp. The address of the element index 2 of the array temp. In one sentence, explain the meanings of each of the remaining four values, with reference to the array temp if appropriate. include int mainO float temp[30] = {15.5, float ptri float copy-tempi 18.0, 17.6, 12.3, 15.4, 15.2, 13.5, 14.2); ptr-&temp [2]; printf("efin", temp[31) printf("edin", ptr) printf ("edIn",copy[5]) printf("%d ", ptr + 1); printf("edIn", sizeof (temp[01)) printf ("8d ", sizeof (copy))
