Program solution:


1. C- Function - Vowel Count(Id-5284)

#include<stdio.h>

int countVowels(char *s){
    int count=0;
    for(int c=0;c<strlen(s);c++){
        if(s[c]=='a'||s[c]=='e'||s[c]=='i'||s[c]=='o'||s[c]=='u'||s[c]=='A'||s[c]=='E'||s[c]=='I'||s[c]=='O'||s[c]=='U'){
            count+=1;
            
        }
    }
    return(count);
}


int main(){
    char str[1001];
    scanf("%s",str);
    printf("%d", countVowels(str));
}

2. C-Function - Average (Id-5303)

#include<stdio.h>

void setAverage(int values[], int n, double *average){
    double a;
    for(int i=0;i<n;i++){
        a+=values[i];
    }
    *average=(a/(n*1.0));
}

int main(){
    int N, index;
    double average=0;
    scanf("%d",&N);
    int values[N];
    for(index=0;index<=N-1; index++){
        scanf("%d", &values[index]);
    }
    setAverage(values, N, &average);
    printf("%.2f", average);
}
