Shifting bits and bytes to create encryption - c

Question

I'm writing a program that encrypts based on bit/byte shifts. This program currently takes in a file, displays the contents, then displays the hex values.
To encrypt the file I am suppose to perform bit/byte shifts. However, I loaded the file into an array and performed shifts through the use of temp swaps. I'm pretty sure the outcome is the same, but I wanted to implement this with the proper bit shifts.
To produce the same results, do I just say load[x>>3] to shift the bits? I'm getting terrible results attempting to implement this.
Below is the entire block of code with a sample output at the end. Thanks in advance to everyone for your time.
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char* argv[]) {
FILE *fp;
char ch;
char load[100];
int count1 = 0;
int count2 = 0;
int i = 0;
fp = fopen("load.txt", "r");
if (fp == NULL)
{
perror("Exiting, an error occured while opening\n");
exit(EXIT_FAILURE);
}
while((ch = fgetc(fp)) != EOF)
{
printf("%c", ch);
++count1;
}
fclose(fp);
fp = fopen("load.txt", "r");
if (fp == NULL)
{
perror("Exiting, an error occured while opening\n");
exit(EXIT_FAILURE);
}
printf("\n\n");
while((ch = fgetc(fp)) != EOF)
{
printf("%x ", ch);
++count2;
}
fclose(fp);
printf("\n\n");
printf("Count1: %d, Count2: %d \n", count1, count2);
printf("\n\n");
fp = fopen("load.txt", "r");
if (fp == NULL)
{
perror("Exiting, an error occured while opening\n");
exit(EXIT_FAILURE);
}
i = 0;
while((ch = fgetc(fp)) != EOF)
{
load[i++] = ch;
}
load[i] = 0;
fclose(fp);
// for(i = 0; i < 100; ++i)
// {
// printf("%s", load);
// }
printf("\n\n");
for(i = 0; i < 50; ++i)
{
printf("%x ", load[i]);
}
// printf("\n index i: %c\n", load[0]);
//shift bytes
char temp, temp2, temp3, temp4;
temp = load[7];
load[7] = load[11];
load[11] = temp;
temp2 = load[8];
load[8] = load[12];
load[12] = temp2;
temp3 = load[9];
load[9] = load[13];
load[13] = temp3;
temp4 = load[10];
load[10] = load[14];
load[14] = temp4;
printf("\n\n");
for(i = 0; i < 50; ++i)
{
printf("%x ", load[i]);
}
printf("\nAfter byte shift: \n %s", load);
//shift bites
temp = load[6];
load[6] = load[4];
load[4] = temp;
temp2 = load[5];
load[5] = load[3];
load[3] = temp2;
printf("\nAfter bit shift: \n %s", load);
printf("\n\n");
for(i = 0; i < 50; ++i)
{
printf("%x ", load[i]);
}
printf("\n\n");
return 0;
}
