Menu problem, HELP!!

i want to make a menu using C but after i typed all the functions included in the menu, i don't know how to put them together (i am a beginner)and form a complete program like this:

1. count no. of words
2. count no. of vowels
3. Count no. of capital letters
4. Reverse text
5. Capitalize the first character

Please enter your choice: _



here are codes that i hv typed so far:

Code:

---

/*count words*/
#include <stdio.h>
#include <string.h>

int main()
{
        char text[800];
        int count=0, i;

        printf("Please input text: ", stdout);
        fgets(text, 800, stdin);

        if (text[0] != ' ')
                count++;

        for (i=1; i<strlen(text); i++)
                if ((text[i-1] == ' ') && (text[i] != ' '))
                        count++;

        printf("\nThe total number of words is %d.\n\n", count);

        return 0;
}

Code:

---

/*count vowels*/
#include <stdio.h>
#include <string.h>

int main()
{
        char sentence[800];
        int a=0, e=0, i=0, o=0, u=0;
        int j;

        printf("Please input text: ", stdout);
        fgets(sentence, 800, stdin);

        for (j=0; j<strlen(sentence); j++)
        {
                if ((sentence[j] == 'a') || (sentence[j] == 'A'))
                        a++;
                else if ((sentence[j] == 'e') || (sentence[j] == 'E'))
                        e++;
                else if ((sentence[j] == 'i') || (sentence[j] == 'I'))
                        i++;
                else if ((sentence[j] == 'o') || (sentence[j] == 'O'))
                        o++;
                else if ((sentence[j] == 'u') || (sentence[j] == 'U'))
                        u++;
        }

        printf("\nThe total number of 'a' is %d\n", a);
        printf("The total number of 'e' is %d\n", e);
        printf("The total number of 'i' is %d\n", i);
        printf("The total number of 'o' is %d\n", o);
        printf("The total number of 'u' is %d\n\n", u);

        return 0;
}

Code:

---

/*count capital letters*/
#include <stdio.h>
int main()
{

        int i, count=0;
        char sentence[800];

        printf("Please input text: ", stdout);
        fgets(sentence, 800, stdin);
        sentence[strlen(sentence)-1]='\0';

        for(i=0;i<strlen(sentence);i++){
                if(sentence[i]>='A'&&sentence[i]<='Z')
                        count++;
        }
        printf("\nThe total number of capital letters is %d\n\n",count);

        return 0;
}

---

Code:

---

/*reverse text*/
#include <stdio.h>
#include <string.h>

int main()
{
        char plain[800], cipher[800];
        int i, len;

        printf("Please input text: ", stdout);
        fgets(plain, 800, stdin);
        plain[strlen(plain)-1] = '\0';

        len = strlen(plain);

        for (i=0; i<len; i++)
                cipher[i] = plain[len-i-1];

        cipher[len] = '\0';

        printf("\nThe result is: %s\n\n", cipher);

        return 0;
}

Code:

---

/*capitalize 1st char*/
#include <stdio.h>
#include <string.h>

int main()
{
        char sentence[800];
        int i;

        printf("Please input text: ", stdout);
        fgets(sentence, 800, stdin);

        if ((sentence[0] >= 'a') && (sentence[0] <= 'z'))
                sentence[0] = sentence[0] - 'a' + 'A';

        for (i=1; i<strlen(sentence); i++)
                if ((sentence[i-1] == ' ') && (sentence[i] >= 'a') && (sentence[i] <= 'z'))
                        sentence[i] = sentence[i] - 'a' + 'A';
                else if ((sentence[i-1] != ' ') && (sentence[i] >= 'A') && (sentence[i] <= 'Z'))
                        sentence[i] = sentence[i] - 'A' + 'a';

        printf("\nThe result is: %s\n\n", sentence);

        return 0;
